The answer is C.4/7
Step-by-step explanation:
First of all, parallel lines have the same gradient (slope), so if you find the slope for line A this will be the same slope as the line parallel to it (line A).
Step 1: find any two points from line A.
point 1: (0,4) Where, and
point2: (-7,0) Where, and
Step2: write the formula of the slope:
Step3: substitute the numbers in the formula:
Step4: simplify the formula to get the answer to the slope:
So the answer is:
C. 4/7
(note: this is the slope of line A and any line parallel to line A)
