Answer is A, different slopes

Ok, so to solve this, you have to have the equations in standard form, which is:

y=mx+b

where m is the slope of the line

So, for the first equation, the slope is 4

For the second equation, you have to rearrange it so it's in standard form.

-15x+3y=-45

Begin to isolate y by performing the opposite operation of adding 15x on both sides of the equation

The 15x will cross out on the left

-15x + 15x = 0x = 0

The result on the right will be 15x - 45

3y = 15x - 45

To completely isolate y, perform the opposite operation by dividing 3 on both sides of the equation by 3.

When you do that, divide each term by 3

The 3's on the left will cross out

3y ÷ 3 = 1y = y

15x ÷ 3 = 5x

-45 ÷ 3 = -15

y = 5x-15

So, the slope of the line is 5
