Answers

I'll Give You Some Hints:

Let's Look at C.

In C, the triangle is translated 2 units to the right. Which means that it cannot be a reflection.

Let's Look at B.

In B there is a sideways triangle. That means it's a Rotation. Which means it's not Reflected.

Lastly, Let's Look at A.

To get from the original triangle to the triangle in A, you have to reflect twice. Once along a vertical line, and then along a horizontal line.

point slope and slope intercept ​

Answers

Answer:

Step-by-step explanation:

Observe what happens to y if we move from x = 1 to x = 9:  y decreases by 2.  Thus, the slope of the line in question is m = rise / run = -2/8, or -1/4.

Writing the equation in point-slope form, y - k = m(x - h), we get:

y - 7 = (-1/4)(x - 1)      (point-slope form)

Solving for y results in the slope-intercept form:

y = 7 - x/4 + 1, or

y = (-1/4)x + 8     (slope-intercept form)
