Write an equation in slope-intercept form from the points (0, 3) and (-4,-1)
Answer:
y = x + 3
Step-by-step explanation:
Slope-intercept form is represented by the formula [tex]y = mx + b[/tex]. We can write an equation in point-slope form first, then convert it to that form.
1) First, find the slope of the line. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] and substitute the x and y values of the given points into it. Then, simplify to find the slope, or [tex]m[/tex]:
[tex]m = \frac{(-1)-(3)}{(-4)-(0)} \\m = \frac{-1-3}{-4-0} \\m = \frac{-4}{-4} \\m = 1[/tex]
Thus, the slope of the line must be 1.
2) Now, since we know a point the line intersects and its slope, use the point-slope formula [tex]y-y_1=m(x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex]. From there, we can convert the equation into slope-intercept form.
Since [tex]m[/tex] represents the slope, substitute 1 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:
[tex]y-3=1(x-0)\\y-3 = x\\y = x + 3[/tex]
if 2x^2-5x+7 is subtracted from x^2+2x-11, what is the leading coefficient?
a)-18
b)2
c)-2
d)7
Answer:
-1
Step-by-step explanation:
2x² - 5x + 7 is subtracted from x² + 2x - 11, so
(x² + 2x - 11) - (2x² - 5x + 7)
x² + 2x - 11 - 2x² + 5x -7 (Distribute the negative)
-x² + 7x - 18 (Combine like terms)
The leading coefficient is the coefficient of the first term, so it is -1.

The temperature was -2°F in the afternoon and is now -30°F. How many degrees did it drop?
Answer:
28°
Step-by-step explanation:
Let's take 'x' as the number of how much degrees it dropped. So this is how the equation will look like:
-2 - x = -30
It is '-x' since the temperature 'decreased', so you must a subtract.
Take -30 to the other side and substitute it with '-x'. Since both the terms are shifted, -30 will be +30 and -x will be +x (which is equivalent to x).
x = -2 + 30
x = 28°
∴ There was a 28° drop.

At the last basketball game ,12 out of the first 48 people who entered the stands were wearing a coat. if this sample is representative of the 200 people attending the game , about how many are wearing a coat?
Answer: attending the game
Step-by-step explanation:
Given: 12 out of the first 48 people who entered the stands were wearing a coat.
That means, Proportion of people wearing coat = [tex]\dfrac{12}{48}=\dfrac{1}{4}[/tex] (People wearing coat divided by Total people)
Total people in the sample attending the game= 200
Number of people wearing a coat = [tex]200\times\dfrac14[/tex]
[tex]=50[/tex]
Hence, 50 people are wearing a coat.

Work out the equation of the line which has a gradient of 1/2 and passed through the point (4,-2)
Answer:
2y-x = -8
Step-by-step explanation:
The equation if a line ilin point slope form is expressed as;
y-y0 = m(x-x0)
M is the slope
(X0,y0) is the point
Substitute
y - (-2) = 1/2(x-4)
y+2 = 1/2(x-4)
2(y+2) = x-4
2y+4 = x-4
2y-x = -8
Hence the required equation is 2y-x = -8
tan(A+B)=tanA+tanB/1—tanAtanB
