Question

Which function represents a line with a slope of ?4 and a y-intercept of ?2? A) y = 4x ? 2 B) y = ?4x + 2 Eliminate C) y = ?4x ? 2 D) y = ?2x ? 4

Answer 1

A function describes this way is y = 4x + 2

Explanation:

In order to find this, we have to start with slope-intercept form.

y = mx + b

Knowing this, we can then input the slope in for m and the intercept in for b. This will give us the equation.

y = 4x + 2
