1) their slopes are equal but y-intercepts are not equal 2) their slopes are not equal but y-intercepts are equal 3) both slopes and y-intercepts are equal 4) neither slopes nor y-intercepts are equal

Function A describes f(x) = 5x + 2. ('2 more than' means 'add 2', and '5 times x' means '5x'.)

To find function B, calculate the slope using two of the given points in the table.

This creates a partial equation: y = 3x + b. To find b (or the y-intercept), input one coordinate pair from the chart.

This creates the equation of function B: y = 3x + 5.

Now, you can compare the slopes and y-intercepts of function A and function B.

Function A: f(x) = 5x + 2

Function B: f(x) = 3x + 5

These functions do not share a slope nor a y-intercept.

78.59 is the mean

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
