Answer:
Step-by-step explanation:
Answer:
a. When two variables change in the same direction, one remaining larger than the other by the same factor - direct relationship
b. To insert between neighboring points or estimate by taking an average of known values - interpolate
c. A relationship between two variables in which the product remains constant. When one variable increases the other decreases in proportion so that the product is unchanged - inverse relationship
Answer:
The slope in this equation is
.
Step-by-step explanation:
Slope-intercept form: 
m = slope
b = y-intercept
x = variable

Answer:
Infinite Solutions
Step-by-step explanation:
If you look at the equation careful you will see this part "-4y+4y". If you see that the variables cancel each other out leaving 2=2. That means that for any value of y, 2=2. Because the variable cancels itself out it doesn't mater what the variable is. So there is an infinite amount of values you can have for "y".
