Question

Is (3,-1) a solution to y = -7/5x + 4

Answer 1

Answer 2

Plug it in

(3, -1) is in the form of (x, y)

3 is the x value and -1 is the y-value

y = -7/5 x + 4

if that point is a solution to the equation, then it should make it true

Answer 3

I'm still confused @AZ

Answer 4

So it would be -1=-7/5(3)+4

Answer 5

replace x with 3
and y with -1

and solve it

-1 = (-7/5) * 3 + 4

Answer 6

yes, now just multiply it

what is (-7/5) * 3

and then add 4

do you get -1?

if you get -1 then you have -1 = -1

and so that point (3, -1) is indeed a solution

Answer 7

It's -4.2+4=.2

Answer 8

So no it wouldnt i think

Answer 9

Exactly! It's not a solution because we get

-1 = 0.2

and that is not a true statement

Answer 10

Yay, Thank you!!
