The answer is:

y = -5/2x + 8

Work/explanation:

First, I will use the slope formula to find slope:


\sf{m=(y_2-y_1)/(x_2-x_1)}

where:

m = slope;

(x₁, y₁) and (x₂, y₂) are points on the line.

Plug in the data:


\sf{m=(-2-3)/(4-2)}


\sf{m=(-5)/(2)}


\sf{m=-(5)/(2)}

Hence, m = -5/2.

So far, the equation is y = -5/2x + b.

Now, we'll use the first point (2,3) and plug it into the equation to solve for b.

3 = -5/2 (2) + b

3 = -5 + b

-5 + b = 3

b - 5 = 3

b = 3 + 5

b = 8

Hence, the equation is y = -5/2x + 8.
