Using y = mx + b
m = 3 and b = 4
so
equation
y = 3x + b
Problems 5, 7A, and 7C are the only ones with correct answers.
But for 1 - 6, you're also supposed to color in the same amount of the big square,
and for 7, you're also supposed to mark a dot on the number line. You haven't

All of these problems are just changing a fraction to another fraction that's
equivalent but has a different denominator. Whatever the old denominator
was multiplied by to get the new one, the old numerator also has to be
multiplied by the same thing. If you don't do that, then you've changed
the value of the fraction.
You have some more work to do.
The answer is 5 If you dont like this you first see what you can multiple to get to 15 first.
