(-5,-5) , (10,-2)
.
Find the slope:
m=change in y/change in x=(-5-(-2))/(-5-10)=-3/-15=1/5
.
Slope intercept form:
y=mx+b
We have m=1/5:
y=(1/5)x+b
Put in values from one point and solve for b:
Using point (-5,-5):
-5=(1/5)(-5)+b
-5=-1+b
-4=b
Using values for m and b:
y=(1/5)x-4 ANSWER: This is the equation in slope-intercept form.
.
CHECK:
Use the other given point (10,-2):
y=(1/5)x-4
-2=(1/5)10-4
-2=2-4
-2=-2

Use general slope intercept formula
( -5,-5 ) and ( 10, -2 )

Multiply both sides by

----------------------
check answer:
( -5, -5 )

You can check the other point ( 10, -2 )
