Find the slope of the line that passes through the points shown in the table.
Fed [463]
Answer: -2/7
This value is a fraction.

----------------------------------

Work Shown:

The first two rows in the table produce these two points (x1,y1) = (-14,8) and (x2,y2) = (-7,6)

So, x1=-14, y1=8, x2=-7, and y2=6

Plug these four values into the slope formula and simplify
m = (y2 - y1)/(x2 - x1)
m = (6 - 8)/(-7 - (-14))
m = (6 - 8)/(-7 + 14)
m = -2/7

∠A and \angle B∠B are supplementary angles. If m\angle A=(2x-16)^{\circ}∠A=(2x−16) ∘ and m\angle B=(5x+28)^{\circ}∠B=(5x+28) ∘ ,
Otrada [13]

Answer:

The measure of angle A is 32

Step-by-step explanation:

A+B=180

2x-16+5x+28=180

7x+12=180

7x=168

x=24

A=2(24)-16

A=48-16

A=32

Find the slope, or rate of change, from the graph.
TEA [102]

Answer:

-1/2

Step-by-step explanation:

slope is rise over run

or y change divided by x change

to find the slope you need to find points on the graph that meet exact points on the graph

i see (0,1) and (2,0)

to find slope without graph it would be (y2-y1)/(x2-x1)

in this case (0-1)/(2-0)

=-1/2

with graph you can count that it goes down -1 squares and to the right 2 squares

hope this helps
