Question

find intercepts of equation y=2x - 8

Answer 1

Its in slope intercept form y=mx+b where be is the y intercept so the y intercept is (0, -8)

to find the x intercept, plug in 0 for y and then solve for x

Answer 2

x=4

Answer 3

so would it be (4,0)

Answer 4

(4,0),(0,-8)

Answer 5

Correct

Answer 6

can you help with this?

Answer 7

write an equation in point slope form of the line that passes through the given point and with the given slope m

Answer 8

(-6,2) m=3

Answer 9

point slope form is
y-y1=m(x-x1) where m is slope and (x1, y1) is your point

Answer 10

y-2=3(x-5)

Answer 11

Close, y-2=3(x+6)

Answer 12

but it was a negative 6

Answer 13

Since theres a negative in the formula and its a negative 6, it becomes positive.

Answer 14

thanks! also one more.

Answer 15

use point by point plotting to sketch the graph of the function

Answer 16

f(x)=32/x

Answer 17

can you just tell me how to do that? how to plug it in my calc

Answer 18

Do you have a graphing calculator?

Answer 19

yes

Answer 20

Alright, you should be able to just input the equation. instead of f(x)= it might say y=

just put in y=32/x and it should graph it for you

Answer 21

thank you

Answer 22

You're welcome
