Question

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

Answer 1

Equation format of a line \[\frac{x}{a}+\frac{y}{b}=1\] where a is x- intercept and b is y- intercept

Answer 2

\[\frac{-7}{5}x-4y=7\] convert it into the form \[\frac{x}{a} + \frac{y}{b} =1\]

Answer 3

To find x-int: Plug in y=0, solve for x.

To find y-int: Plug in x=0, solve for y.

Answer 4

I used the long method :p

Answer 5

Yours is way, way more complicated than necessary :P I've never even seen it.

Answer 6

Answer 7

It is X=-5(7+4y/7 and Y is Y=- 7(1+x/5)/4 Hope I helped !!
