I need to explain this how do i do that?

To solve, we need to write this in slope-intercept form.

Slope: 3

Point: (1,2)

Slope-intercept form:

y = mx + b (y = y value, m = slope, x = x value, b = y-intercept)

y = 2, m = 3, x = 2, b = ?

We have to solve for b. To do so, we plug in all these values into our formula. Move all values not equal to b to the left of the equation.

Now that we know what b is, we can plug it into our equation. Plug in only the value of the slope and the y intercept.

y = mx + b

y = 3x - 1

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

mean, 40.6
