Question

Find the x- and y-intercepts and graph the equation plotting the intercepts. -2x + 7y=7

Answer 1

y=1

x=-7/2

Answer 2

First solve for y

-2x+7y=7
7y=7+2x
y=(7/7)+(2/7)x
y=1+(2/7)x

For the y-intercept, substitute 0 for x

y=1+(2/7)*0
y=1

For the x-intercept, substitute 0 for y

0=1+(2/7)x
-1=(2/7)x
-7=2x
-7/2=x
