7 x (-2) = - 14

2 x (-5) - 4 = - 14

substitute -5 for x in the equation and -2 for y. this should lead you to get _ = _ , which is your solution

If (−5,−2) lies on the line with equation 7y = 2x−4, you should be able to substitute for x and y and have the equation make sense:

7y=........................= 2x-4

7(-2) = -14 = -10-4 = 2(-5)-4.............CORRECT.

So (-5,-2) is on the line 7y=2x-4............ANS

7y = 2x − 4

(x, y) = (-5, -2)

-14 = -10 - 4

well simply substitute -5 and -2 into the equation to see if the equation is true.

x = -5

y = -2

substituting we have

7(-2) = 2(-5) - 4

-14 = -10 - 4

-14 = - 14

if you don't understand why substituting to check if it lies on the line of that equation, you should graph the equation and check the point -5, -2.
