Question

Find the slope for these two

Answer 1

For the first one, we see that from one point to another it rises one and goes to the left one. This means the slope is 1/-1, which is -1.

For the second one, the slope of the first equation is -1/4, and the slope of the second equation is 4/1, or 4. Since the lines are perpendicular in 2, the two lines will be opposite reciprocals of each other.

Answer 2

1) -1

2) -1/4, 4

Explanation:

1)

The first equation is

y = -x + 5

Comparing with

y = mx + b, we see thqat the slope, m, is -1

1) Answer: slope = -1

2)

The equations are

y = -1/4 x + 2 and

y = 4x + 8

Comparing the two equations with y = mx + b, we see that the slopes are

-1/4 and 4

2) Answer: slope = -1/4; slope = 4
