The table represents some points on the graph of an exponential function. Which function represents the same relationship?

f ( x ) = 18 ( 6 5 ) x f\left(x\right)=18\left(\frac{6}{5}\right)^x f ( x ) = 1 8 ( 5 6 ) x

f ( x ) = 15 ( 5 6 ) x f\left(x\right)=15\left(\frac{5}{6}\right)^x f ( x ) = 1 5 ( 6 5 ) x

f ( x ) = 15 ( 6 5 ) x f\left(x\right)=15\left(\frac{6}{5}\right)^x f ( x ) = 1 5 ( 5 6 ) x

f ( x ) = 18 ( 5 6 ) x f\left(x\right)=18\left(\frac{5}{6}\right)^x f ( x ) = 1 8 ( 6 5 ) x

The table shows the amount of pet food in cups remaining in an automatic feeder as a function of the number of meals the feeder has dispensed. Based on the table, which function models this situation?

f ( n ) = − 3 n + 24 f\left(n\right)=-3n+24 f ( n ) = − 3 n + 2 4

f ( n ) = − 1 3 n + 16 f\left(n\right)=-\frac{1}{3}n+16 f ( n ) = − 3 1 n + 1 6

f ( n ) = − 3 n + 64 f\left(n\right)=-3n+64 f ( n ) = − 3 n + 6 4

f ( n ) = − 1 3 n + 8 f\left(n\right)=-\frac{1}{3}n+8 f ( n ) = − 3 1 n + 8

The table represents some points on the graph of a linear function. Which function represents the same relationship?

h ( x ) = − 3 x − 10.5 h\left(x\right)=-3x-10.5 h ( x ) = − 3 x − 1 0 . 5

h ( x ) = − x − 3.5 h\left(x\right)=-x-3.5 h ( x ) = − x − 3 . 5

h ( x ) = 3 x − 10.5 h\left(x\right)=3x-10.5 h ( x ) = 3 x − 1 0 . 5

h ( x ) = x − 3.5 h\left(x\right)=x-3.5 h ( x ) = x − 3 . 5

Linear function f (x) = x is graphed on a coordinate plane. The graph of a new line is formed by changing the slope of the original line to 2/3 and the y-intercept to 4. Which statement about the relationship between these two graphs is true?

The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up.

The graph of the new line is steeper than the graph of the original line, and the y-intercept has been translated down.

The graph of the new line is steeper than the graph of the original line, and the y-intercept has been translated up.

The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated down.

Which of the following is equivalent to 3x-4y=6 3 x − 4 y = 6

y = 3 4 x − 3 2 y=\frac{3}{4}x-\frac{3}{2} y = 4 3 x − 2 3

y = − 6 7 x y=-\frac{6}{7}x y = − 7 6 x

y = − 3 4 x y=-\frac{3}{4}x y = − 4 3 x

y = 4 3 x + 2 y=\frac{4}{3}x+2 y = 3 4 x + 2
