Answer:
y intercept=15 and slope is 3
Step-by-step explanation:
Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15
to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:
(18-15)/(1-0)
3/1
= 3
6, 1.5, 10, 16, 80, and 2

I believe its B
Step-by-step explanation:
I took this test and im pretty sure I got this one right
Step-by-step explanation:
A function is such that every element in the domain has only 1 image in the range. The domain here are the x-values while the range is the y-values.
However a vertical line can cross the graph more than once. Hence the graph is not a function.
Answer:
x = 2
Step-by-step explanation:
Collinear means that the points A, B and C all lie in a straight line, hence
AB + BC = AC, substitute values
5x - 1 + 14 = 25 - x
5x + 13 = 25 - x ( add x to both sides )
6x + 13 = 25 ( subtract 13 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
