The intercepts are where the function graph crosses an axis. For example, your x-intercept is (5,0) because the function crosses the x-axis at this point. The y-intercepts are (0, +/- 1.5). The domain is whatever x-coordinates are crossed, in this case, -3 < x </= 5. The range includes any y-coordinates that are crossed. -2 < y < 2.

What is the y-intercept of the function, represented by the table of values

AleksandrR [38]

Answer:

9

Step-by-step explanation:

The table is given below

$\left|\begin{array}{c|cc}x&y\\--&--\\-2&15\\1&6\\2&3\\4&-3\\7&-12\end{array}\right|$

We can see that the table represents a linear function since by checking its slope.

Using:

Points (-2,15) and (1,6)
Points (1,6) and (2,3)

$Slope =\dfrac{6-15}{1-(-2)} =\dfrac{3-6}{2-1}=-3$

Therefore, the values represent a linear function.

A linear equation is of the form y=mx+b

Therefore:

y=-3x+b

Using the points (7,-12)

$-12=-3(7)+b\\-12=-21+b\\b=-12+21\\b=9$

Therefore, the y-intercept of the function, represented by the table of values is 9.

Chris’s new car gets 42 miles per gallon. What is the equation that represents y, the total miles driven on x gallons of gas?

Fantom [35]

Answer: I think the answer is B

Step-By-Step Explination:

First you find out what x is by doing 42 multiplying it by 0.1 witch equals 4.2 gallons per mile

Next you figure out what y is by doing 4.2y (witch is 4.2 times y)
