y= mx+b
m= 5/2
b= y-intercept = 5

y= 5/2x + 5

This line can be written as:

y = -2.5*(x - 2)

How to find the linear equation?

We know that this line passes through (0, 5) and (-2, 0).

We want to write the slope-point form of this line, so first let's find the slope. We know that if the slope is m, and the line passes through (h ,k ) then the equation is:

y - k = m*(x - h)

The slope here is:

m = 5/-2 = -2.5

And we can use the point (-2, 0), then we will get:

y - 0 = -2.5*(x - 2)

y = -2.5*(x - 2)
