Answer: slope = 1
Step-by-step explanation:
For two lines to be parallel then they have the same slope , if the slope of line 1 is M1 and then slope of line 2 is M2 , if they are parallel then M1 = M2.
Given; y- 4 = + (x + 8)
Make y the subject of the formula , so that the equation can be in slope - intercept form , that is in the form y = mx + c , where m is the slope and c is the y - intercept.
y - 4 = x + 8
Add 4 to both sides
y = x + 8 +4
y = x + 12
since the coefficient of x is 1 , this means that the slope is 1 , any line that will be parallel to this line must have a slope which is 1
If you would like to solve the following system, you can calculate this using the following steps:
y = x - 20
y = 6 * x
_________
6 * x = x - 20
6 * x - x = -20
5 * x = -20 /5
x = -4
y = 6 * x = 6 * (-4) = -24
If you would like to solve the following system, you can calculate this using the following steps:
y = x + 20
y = 6 * x
_________
6 * x = x + 20
6 * x - x = 20
5 * x = 20 /5
x = 4
y = 6 * x = 6 * 4 = 24
