Question

What is the equation of a line with a slope of -3 and a y-intercept of 4?

A. y= 4x+3
B. y= 4x-3
C. y=-3x-4
D. y=-3x+4

Answer 1

Explanation:

We have,

• Slope (m) = -3
• y-intercept (c) = 4

We know that,

y = mx+c

y = -3x+4

Hence, option (D) is correct.

Answer 2

y = -3x+4

Explanation:

The slope intercept form of a line is given by

y = mx+b where m is the slope and b is the y intercept

y = -3x+4
