Question

What is the equation of a line with slope 2 and a y-intercept of -4 ?

Answer 1

Answer:

y = 2x - 4

Step-by-step explanation:

Using the equation y = mx + b we can write an equation, where m is the slope and b is the y-intercept. Plug in for the variables and you will get your answer.

y = 2x + (-4)

y = 2x - 4

Hope this helps.

Answer 2

Answer:

y=2x-4

Step-by-step explanation:

The equation of a line in slope-intercept form is:

y=mx+b

Where "m" is the slope, "b" is the y-intercept, and "x" and "y" are the x and y coordinates.

We are given the slope and the y-intercept therefore the equation would be:

y=2x+(-4)

y=2x-4
