Which ordered pairs in the form (x, y) are solutions to the equation
7x−5y=28?
Select each correct answer.
A. (4, 10)
B. (−1, −7)
C. (7, 9)
D. (−6, −14)
When I tried to solve for 5y I got 5.6
Answers
Options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
7x - 5y = 28
From the above equation:
y = mx + c
On comparing:
y = (7/5)x - 28/5
m = 7/5
c = -28/5
After plotting the graph of the equation:
From the graph:
B. (−1, −7)
D. (−6, −14) are the ordered pairs in the form (x, y) that are solutions to the equation.
Thus, options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.

I'm not sure what the whole question is, it looks like you're missing a couple of things.
What variable are you trying to solve?
if it's x, the answer is
6x + y = 16
6x = 16 - y
x = 8/3 - y/6
Solve: x/3 + 6 - 2x = -6. Please show your work.

The product of three integers is -3. Determine the possible values for the three factors.
Answers
Answer:
1. The overall change is -150 feet. 50 times 5 is 150 feet, and the mountain climber descended. Therefore, the change is -150 feet in elevation.
2.The required integer is -18
Step-by-step explanation:
2. The temperature dropped 3°c every hour,
So, the change in temperature every hour = -3°C
Total number of hours for which the temperature were changed = 6,
Thus, the total change in temperature = change for an hour × total number of hours,
= -3° × 56
= -18°
Hence, the integer that represents the change in temperature is -15.

1. Is -250.
2. Is 18
