Probably the easiest way to do these is to convert them to slope intercept form by solving for y. When we have y=mx+b, we read off the slope m.

-5x + 2y = 10

Add 5x to both sides,

2y = 5x + 10

Divide both sides by 2,

y = (5/2) x + (10/2)

Obviously 10/2=5 but we don't care about that for this problem. We read off the slope as

Answer: 5/2, last choice

12 = 4x - 6y

Adding 6y and subtracting 12,

6y = 4x - 12

Dividing by 6,

y = (4/6) x - (12/6)

y = (2/3) x - 2

Answer: 2/3

Consider the function g:

Alja [10]

Another way to ask this question: where the x-value of function g equals 12, what's the y-value?

remember that function notation is like so: f(x), g(x), h(x)... so the number in the parentheses is an x-value from the function.

look through your points and find the one that represents an x-value of 12. (12, 19) is the point, and 19 is your output--so, g(12) = 19.
