Question

find the x- and y- intercept of the line. -7/5x-4y=7

Answer 1

put x=0 and calculate y
put y=0 and calculate x

Answer 2

Plug in 0 for x then 0 for y.
-7/5(0)-4y=7
-4y=7
(0, -7/4)

-7/5x-4(0)=7
-7/5x=7
x=-5
(-5, 0)

Answer 3

I have to choose from 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 this is the only one I just don't grasp. Thanks

Answer 4

duh, it's D right?

Answer 5

To calculate y intercept put 0 in place of x in the equation:
then it becomes=> -4y=7
so y= -7/4
so point is (0,-7/4)
To calculate x intercept put 0 in place of y in the equation:
then it becomes=> (-7/5)x=7
so x= -(7*5)/7
=> x= -5
so point is (-5,0)
