Answer 1

y=
`(3)/(2)`x -1

Explanation:

To find slope I first found the two points on the graph which were (0, -1) and (2, 2). Then I used rise over run to find the slope the point went up 3 units and to the right two units.

then to find the y intercept I found a pint of the graph where the line had passed through the y-intercept line on the graph which just so happened to be -1.

Hope this helps!!

If I am wrong, please tell me, I enjoy learning from my mistakes:)

Answer 2

y = 3/2 - 1

Explanation:

First let's take two coordinates in the line.

( 2 , 2 ) ( 0 , -1)

You can use y = m x + c to find the equation of the line.

Here,

m → slope

c → y - intercept

( 2 , 2 ) ( 0 , -1)

↑ ↑ ↑ ↑

( x1 , y1 ) ( x2 , y2 )

First let's find the slope of the line.

m = ( y1 - y2) / ( x1 - x2)

m = ( 2 - (-1) ) / (2 - 0 )

m = ( 2 + 1 ) / 2

m = 3 / 2

Now let's find the y - intercept of the line.

For that, let's use ( 0 , -1 ) coordinate

y = m x + c

y = 3/2 × 0 - 1

y = 0 - 1

y = ( - 1 )

Therefore, the equation of the line is,

y = 3/2x - 1

Hope this helps you :-)
