6. Identify the slope of a line parallel to the given

line.

y - 4 = + (x + 8)

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
