Answer:
Step-by-step explanation:
Slope intercept form is y=mx+b where m is slow and b is y intercept. since we dont have this info we will have to do some work to solve.
1. find slope. this is change in y du used by change in. so we take the two points given and subtract the y values and divide by difference of x values
m=(8-2)/(-3--1)=6/-2=-3
2
use point slope formula and simplify. this is y-y1=m(x-x1) where (x1,y1) is a point on the l in ne. you can pick either point it doesn't matter. we will use (-1,2)
y-2=-3(x+1)
simplify to slope intercept by solving for y
y-2=-3x-3
y=-3x-1
so we have slope -3 and y intercept -1
Since it’s perpendicular tu have to flip the slope and change the sing which in this case would be -1/5
Then you put the equation together:
y-7=-1/5(x-5)
Distribute:
y-7=-1/5x+1
Add the 7 to both sides of the equation:
y-7=-1/5x+1
+7 +7
And the final answer is: y=-1/5+8
