Question

What is the slope of the line l described by the equation below? y=-2x+4

Answer 1

y = -2x + 4 slope is -2

Explanation:

that's what I got

Answer 2

The slope of the line would be -2.

Explanation:

Because the equation is a line, the slope is the same throughout the entire graph on the equation.

Lets let f(x)=y=-2x+4.

f(0) = -2(0) + 4 = 4

f(0)=4

f(1) = -2(1) + 4 = 2

f(1)=2

Use the equation to find slope.

m(slope) =
`(2-4)/(1-0)` =
`(-2)/(1)` = -2

The slope would be -2.

Or:

Use the equation y = mx + b where m=slope.

In the equation y=-2x+4, m=-2.

The slope is -2.
