How do you find the slope of the line passing through the points (-4,7) and (-4,-9)?

Explanation:

Slope Formula

m = (y2-y1)/(x2-x1)

m = (-9-7)/(-4-(-4))

m = (-9-7)/(-4+4)

m = -16/0

We cannot divide by zero, so the slope is undefined.

All vertical lines have an undefined slope because any two points on this line will have x coordinates of the same value. Those x coordinates subtract to 0.

the areas of two similar triangles are 18 cm2 and 8 cm2. one of the sides of the first triangle is 4.5 cm. what is the length of the corresponding side of the other triangle?

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
