Question

Which equation below has a slope greater than the slope of the line shown above?

A. y = 2 x + 2
B.y = 3x - 1
C. y = - 3
D. y = 4 + 1.75 x​

Answer 1

B.y = 3x - 1

Explanation:

Pick two points on the line

(0,1) and (2,5)

The slope using the slope formula

m = (y2-y1)/(x2-x1)

= ( 5-1)/(2-0)

= 4/2

= 2

We want a slope that is greater than 2

The slope intercept form of the equation is

y = mx+b where m is the slope

y = 3x - 1 has a slope of 3 which is greater than 2
