Rise over Run
Put the amount you go up or down on the Y-axis over how much you go right or the x-axis
the Y-intercept is found simply by looking where the graph crosses the y, if the equation is written instead of graphed, graph it using a graphing calculator, then use the information I gave you previously : )
Answer:
The y intercept is (0,-22)
Step-by-step explanation:
The y intercept is the value when x =0
Y=5x-22
y = 5*0 -22
y = -22
The y intercept is (0,-22)
Every transformation like
![f(x)\mapsto f(x)+k](https://tex.z-dn.net/?f=%20f%28x%29%5Cmapsto%20f%28x%29%2Bk%20)
translated the graph vertically, k units up if k is positive, k units down if k is negative.
So, in your case, we have that
is the same graph as
, except it's shifted 1 unit down.
C. The answer is C because the total amount of students is 14, and there are 4 boys, which makes the ratio 4 boys to 14 students in total. 4 and 14 are both divisable by 2, so divide 4 to get 2 and divide 14 to get 7. This leaves you with 2 and 7. The ratio would be 2 boys to 7 total students. Hope this helped
