Answer 6

Can you calculate the slope of the line from the two points given?

Answer 7

Answer 8

THE SLOPE IS -1/3

Answer 9

first you plug in the numbers for y=mx+b (the equation of the line)

so you already have the m, now you need the b

Answer 10

and how do i do that????

Answer 11

m=slope
b=y-intercept

Answer 12

That means where on the Y-axis is the line going through?

Answer 13

i have to use the point slope formula y-y1=m(x-x1)

Answer 14

You are given \[\left( x_1,y_1 \right) \text{ and }\left( x_2,y_2) \right)\]Calculate slope m using\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]Then substitute m, y1 and x1 into the point-sloep form.

Answer 15

y-(-1)=-1/3(x-(-3) thats all i have

Answer 16

Very good. You can still simplify a bit. Try to simplify y--1 and x--3.

Answer 17

y=-1/3x-2?

Answer 18

When you subtract a negative number, it becomes an addition. For example, x-(-5) simplifies to x+5. There are two instances of this in your earlier solution. Try simplifying them as I've shown here.

Answer 19

so im wrong

Answer 20

Yes, y=-1/3x-2 is incorrect. Back up one step and simplify where you are subtracting negative numbers
