The y-intercept is being changed. In the equations given we are using the formula (y=mx +b), b means the y intercept. In this we are changing the y intercept from 2 to -1. There is nothing else being changed.
Answer:
Step-by-step explanation:
You would first distribute -8 into the parenthesis:
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
Answer:
5y + 4 and 7y + 4 - 2y
Step-by-step explanation:
Look at the second choice:-
5y + 4 and 7y + 4 - 2y
Simplifying the second expression:-
7y + 4 - 2y
= 5y + 4
So both expressions are equivalent . Therefore if you plug in 2 or 5 the results will be the same.
