Answer:
y = 3.5x - 12.5
Step-by-step explanation:
First, find the slope using rise over run ( y2 - y1 / x2 - x1) with the 2 points:
(-2 - 5) / (3 - 5)
-7/-2
= 3.5
Then, plug the slope and a point into y = mx + b to solve for b:
y = mx + b
5 = 3.5(5) + b
5 = 17.5 + b
-12.5 = b
Plug the slope and the y intercept into the equation y = mx + b
y = 3.5x - 12.5 will be the equation
Answer:
y=7/2x-12.5
Step-by-step explanation:
use the y=mx+b and the method
7/2= thats ur slope
now plug in the slope and one of the point into the y=mx+b method
-2=7/2(3)+b
-2=21/2+b
subtract 21/2 both sides
-25/2 or -12.5
ik this doesnt make sense but hope this helps

Answer:
(x+3) x+7 is the answer for the first question if it's the same way my school does it. Whatever you put in parentheses is the opposite of what you think. + is going to the left. - is going to the right but those only apply when in parentheses.
