Question

The graph of which equation has a slope of 4?

(1) y = 4x -3 (3) y = -4x + 3
(2) y = 3x - 4 (4) y=-3x + 4
Please help :( I don’t get it

Answer 1

(1)

Explanation:

The equation of a line in slope- intercept form is

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

We are looking for an equation of the form

y = 4x ± c ( since slope m = 4)

The only equation which fits the description is

y = 4x - 3 → (1)
