Answer:
y=x+6
Step-by-step explanation:
If you need to find a standard linear equation from two points, you have to first find the slope, then find the y intercept.
To find the slope, you should do the change in y over the change in x.
that would be:
(4-9)/(-2-3)
(-5)/(-5)
the slope is 1
plug that in along with values of x and y taken from known point (3,9) to the standard equation of a linear relationship:
y=mx+b
m=1
y=9
x=3
b=?
9=(1)(3)+b
9=3+b
b=6
The equation of the line would be y=x+6
