6. identify the slope of a line parallel to the given
line.
y- 4 = + (x + 8)

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
