What is the slope of a line parallel to line A?
A. -4/7
B. -7/4
C. 4/7
D. 7/4

Answer:
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).
point 1: (0,4) Where, [tex]x_{1} =0[/tex] and [tex]y_{1}=4[/tex]
point2: (-7,0) Where, [tex]x_{2} =-7[/tex] and [tex]y_{2} =0[/tex]
[tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
[tex]m=\frac{0-4}{-7-0}[/tex]
[tex]m=\frac{-4}{-7}[/tex]
[tex]=\frac{4}{7}[/tex]
C. 4/7
(note: this is the slope of line A and any line parallel to line A)
