On a coordinate plane, a line goes through points (negative 2, 0) and (0, 2). Study the graph of the line. Use the drop-down menu to find its equation. The equation of the line is .
Answer:
[tex]y=x+2[/tex]
Step-by-step explanation:
Finding Slope:We are given the points (-2,0) and (0,2).
Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{2-0}{0-(-2)}=\frac{2}{2} = 1[/tex]
The slope is one.
Finding the Y-intercept:So far we have [tex]y=x+b[/tex].
We can use a point to find 'b', the y-intercept.
I will use (0,2):
[tex]2=0+b\\2-0=0-0+b\leftarrow \text {Subtraction Property of Equality} \\\boxed {2=b}[/tex]
The y-intercept is 2.
Final Equation:The equation of the line is [tex]y=x+2[/tex].
In slope equations, the 'one' is commonly hidden.
Answer:
y = x + 2

Answer:
[tex] \boxed{c = -17} [/tex]
Step-by-step explanation:
[tex] = > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17[/tex]
Answer:
c = -17
Step-by-step explanation:
→Distribute the 7 to (-7c - 19):
3 - 7c - 20c = -49c - 133 + 14c
→Add like terms (-7c and -20c, -49c and 14c):
3 - 27c = -35c - 133
→Add 35c to both sides:
3 + 8c = -133
→Subtract 3 from both sides:
8c = -136
→Divide both sides by 8:
c = -17

On a coordinate plane, a line goes through points (negative 4, 0) and (0, 1).
Cameron
On a coordinate plane, a line goes through points (0, 4) and (1, 0).
Ellis
On a coordinate plane, a line goes through points (0, negative 4) and (2, 0).
Braden
On a coordinate plane, a line goes through points (0, 1) and (4, 0).
Which student graphed a linear function with a y-intercept at –4?
Rhett
Cameron
Ellis
Braden
Answer:
ellis
Step-by-step explanation:
The student who graphed a linear function with a y-intercept at -4 is Ellis.
Option C is the correct answer.
We have,
The student who graphed a linear function with a y-intercept at -4 is Ellis.
Looking at the given information, Ellis's line goes through points (0, -4) and (2, 0).
The y-coordinate of the y-intercept is -4, which matches the requirement.
Therefore, Ellis is the student who graphed a linear function with a y-intercept at -4.
Thus,
The student who graphed a linear function with a y-intercept at -4 is Ellis.

10 Which of the following represents the
domain of the function F(x) = 2x + 15?
3
Answer:
Domain is x ∈ R
Step-by-step explanation:
There weren't any options given, but for f(x) = 2x + 15, the domain is x ∈ R.
This is because the graph is a linear function, which exists for all values of x. You can express this in lots of different ways, but R (all reals) is the conventional way to do it.
In case you don't know what a domain is: it is a set of numbers that the x-values of an equation can fit into.
Example:
f(x) = [tex]x^{2}[/tex] -> x ∈ R
This is because, if you draw a quadratic graph, you can see that the values of x are neverending.

[tex] \frac{x}{2} = - 7[/tex]
Answer:
x = -14
Step-by-step explanation:
[tex]\frac{x}{2}[/tex] = -7
multiply 2 on both sides
the 2's cancel out on the fraction side, leaving x = -7(2)
multiply -7 and 2 to get -14
x = -14
Answer:
-14
Step-by-step explanation:
We must find out what divided by 2 equals -7
So we work backwards
2(-7)
2(-7)=-14
When multiplying negative and positive you get negative
Plug in -14 in x
-14/2=-7
