Hi there.

Y = 2x + 3
Solve for y when x = 3
The first thing we need to do is replace x by the 3 in the equation.
Y = 2(3) + 3
Y = 6 + 3
Y = 9
Thus, your answer is : C

What is y-value when x equals -12? y =-200 - 6(x)

Arada [10]

Hi,

Solving:

$x = - 12 \\ y = - 200 - 6( x) \\ y = - 200 - 6( - 12) \\ y = - 200 + 72 = \underline{ \underline{ - 128}}$

Answer: y = -128

Hope this helps.
