Question

Write an equation in standard form that has a y-intercept at (0,-3) and also contains the point (4,5).

Answer 1

Below

Explanation:

Find the slope between the two given points

(y1-y2) / (x1-x2) <==== does not matter which you assign as point 1 or 2

(-3-5) / (0-4) = -8/-4 = 2

now set up equation using point-slope form (use either point)

y-5 = 2 (x-4) re-arrange

y -5 = 2x - 8

2x - y = 3
