let's clean it up ...
times 5
-7x - 20y = 35
7x + 20y = -35
for the x-intercept, let y = 0
in your head: x = -5
for the y-intercept, let x = 0
y = -35/20 = -7/4
Find the x- and y-intercept of the line.
-7/5x -4y = 7
A.
x -intercept is -7/4; y-intercept is 5
B.
x -intercept is 5; y-intercept is 7/4
C.
x -intercept is 5; y-intercept is -7/4
D.
x -intercept is -5; y-intercept is -7/4
