Question

What are the y values of the equation y = 3x + 4 at x values -1, 0, 1, 2​

Answer 1

-2; 1; 4; 7

Explanation:

To solve for y, plug the x value in to the expression

y = 3(-1) + 1

y = -3 + 1

y = -2

When x = -1, y = -2

y = 3(0) + 1

y = 0 + 1

y = 1

When x = 0, y = 1

y = 3(1) + 1

y = 3 + 1

y = 4

When x = 1, y = 4

y = 3(2) + 1

y = 6 + 1

y = 7

When x = 2, y = 7
