Question

Write an equation in slope-intercept form for the line with intercept -3 and slope-2 .

Answer 1

y = -2x - 3

Explanation:

When we have the slope and the y-intercept, we can write the line's equation using y = mx + b (slope-intercept) form.

For this equation, m is the slope and b is the y-intercept.

The problem told us that m = -2 and b = -3.

Therefore, our equation is this:

y = -2x - 3

Answer 2

y = -2x - 3

Explanation:

The slope intercept equation comes as follows:

y=mx + b

m is the slope in front of the x. Therefore, when you have a slope, in this case, -2, just put the number in front of x.

Next, the y intercept is the number in which the line crosses the y-axis on the Coordinate Plane. In this case, it is -3. Therefore, replace b with the number. Therefore, you get the equation:

y=-2x-3
