Help! I've been trying to work this out for a while and I still don't understand it!

Pick two points from the graph. X1 y1 and x2 y2. Example points from your graph:

(4,1) and (-4,3)

x1=4

y1=1

x2=-4

y2=3

Step-by-step explanation:

To find slope take the points you got from graph and put it into the equation y2-y1/x2-x1

3-1/-4-4=-2/8=-1/4

Then take that slope u got and plug into this equation to find equation of the line

y-y1=m(x-x1)

y-1=-1/4(x-4)=y-1=1/4x+(1/4)(4)

y-1=-1/4x+1

+1 +1

——————

y=-1/4x+2 ANSWER CHECK

m=slope! Which is -1/4

y=-1/4x+2 is your answer!!

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
