y = 2x + 2.5 is the correct answer.

Slope-intercept form is y = mx + b where "m" equals slope and "b" equals the y-intercept.

The equation for figuring out the slope is


( {y_{_(2)} - y_{_(1)} ) divided by
( x_{_(2)} - x_{_(1)} )

(-3 - 1) ÷ (1 - 3)

-4 ÷ -2 = 2

So, the slope is 2

The y-intercept is 2.5 because "y" equals zero, "x" equals 2.5 on the line.

So, the y-intercept is 2.5

The answer is y = 2x + 2.5

Please let me know if I am wrong.
