What is the equation of the line with an x-intercept of - 1and a y-intercept of 2

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have y-intercept b = 2. Therefore y = mx + 2.

x-intercept = - 1 for y = 0. Substitute:

0 = m (-1) + 2 subtract 2 from both sides

-2 = - m change the signs

m = 2

Therefore y = 2x + 2.

The standard form: Ax + By = C.

2x + 2 = y subtract 2 from both sides

2x = y - 2 subtract y from both sides

2x - y = - 2
