Answer:
A <em> </em><em>and</em><em> </em><em>E</em><em> </em><em>is</em><em> </em><em>true</em><em>. </em><em>BCD</em><em> </em><em>is</em><em> </em><em>False</em>
Step-by-step explanation:
Let convert this into slope intercept form
So now let answer these questions,
A is TRUE the slope is the number in front of the x value. It is 20 so a is true.
B is False, Using (0, 500) The equation is wrong
C is false, we have a positive slope so it shifts upward from left to right.
D is false
the slope isn't 200.
E Is true the y intercept is when the x value is 0, what is the y value so plug it in we get
It equal 50.
