Question

Find an equation of the line passing through the pair of points (4,5) and (6,9) . Write the equation in the form Ax+By=C .

Answer 1

-2x + y = -3

Explanation:

Find the slope:

9 - 5 / 6 - 4 = 4/2 = 2

Put it in point-slope form:

y - 5 = 2(x - 4)

rearrange:

y - 5 = 2x - 8

y - 2x = -3

-2x + y = -3
