Question

Find the y-intercept of the line that passes through (2, -3) with slope 4.

Answer 1

y- intercept = - 11

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c

To find c substitute (2, - 3) into the equation

- 3 = 8 + c ⇒ c = - 3 - 8 = - 11 ← y- intercept
