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
