Question

Which equation represents a slope of -4 and y-intercept of (0,2)?

y = −4x + 2

y = −2x + 4

y = −2x − 4

y = 4x − 2

Answer 1

Answer:

  y = −4x + 2

Step-by-step explanation:

The slope intercept form of the equation for a line is ...

  y = mx + b . . . . . . where m is the slope and b is the y-intercept (0, b)

Here, you are given a slope of -4 (m=-4) and a y-intercept of (0, 2), so b=2. When you put these values in place of the corresponding variables, you get ...

  y = -4x +2
