Question

The graph of which

equation has a slope
of 2? Explain
your reasoning.
or show
A) y = 2x-3
B) y = -2x + 3
C) y = 3x - 2
D) y=-3x

Answer 1

A.

Explanation:

we can compare the lines given with the general form of a line
`y=mx+c`. here,
`m` is the slope.

the first line,
`y=2x-3`, does have
`m=2` when compared.

the second line has
`m=-2`.

the third has
`m=3.`

the fourth has
`m=-3`.

thus, the line with slope 2 is line A.

Answer 2

A

Explanation:

the equation of a line in slope- intercept form is

y mx + c ( m is the slope and c the y- intercept )

All of the options are in this form

A :y = 2x - 3

has slope m = 2

B : y = - 2x + 3

has slope m = - 2

C y = 3x - 2

has slope m = 3

D: y= - 3x

has slope m = - 3

Then A has slope m = 2
