Question

A line whose slope is 4 and passes through the point (0, -9) lies on the line whose equation is:

Answer 1

y = 4x - 9

Explanation:

Use the formula:

y = mx + b

Where m is the slope, b is the y-intercept.

The slope is 4.

y = 4x + b

The y-intercept is -9 because it passes through (0, -9).

y = 4x - 9
