Question

Y = 7x - 3

Choose 1 answer:
А
Only (1.4)
Only (-1,-4)
Both (1, 4) and (-1,-4)
Neither

Answer 1

only (1,4)

Explanation:

To find the answer, we simply substitute the x and y values into the equation.

Let‘s try (1,4)

x=1 y=4

4=7(1) -3

4=4

this is correct.

Let’s try (-1,-4)

x=-1 y=-4

-4=7(-1) -3

-4 = -7 -3

-4 = -10

clearly, that is false.

only (1,4)

hope that helps!
