Answer 7

Take two points from the line and find the slope.

Answer 8

Please someone help me!!

Answer 9

Ok

Answer 10

We can find the equation of the line using the slope-intercept equation of a line.

Answer 11

if one point is \(\sf (x_1,y_1)\) and the other point is \(\sf (x_2,y_2)\) then the slope is \(\sf\large \frac{y_2-y_1}{x_2-x_1}\)

Answer 12

The slope-intercept equation of a line is:

\(y = mx + b\)

where m = slope, and b = y-intercept.

Answer 13

^ exactly

Answer 14

Let's find the y-intercept first.
Look at the graph, and see at what point on the y-axis does the line cross the y-axis?

Answer 15

and find the slope

then to find the y-intercept, see where the line crosses the y-axis

Answer 16

ok

Answer 17

y=1

Answer 18

Yes, that's the y-intercept

Answer 19

Correct.
That means we have b = 1.
We can plug in b into our equation:

\(y = mx + 1\)

Answer 20

Now we need the slope.

Answer 21

To find the slope, first you need to find two points of the liner that are easy to read.

Answer 22

4/3 is the slope

Answer 23

A point that is easy to read is a point on the line that is on a grid intersection.

Answer 24

You are correct. m = 4/3

Answer 25

Now we plug in the slope for m.

\(y = mx + b\)

\(y = \dfrac{4}{3} x + 1\)

Answer 26

Ok so that means y=4/3+1

Answer 27

That is the equation of the line.

Answer 28

Don't forget the x.
