Question

1. What is the slope of the line on the coordinate plane? (Please remember to write in fraction)

2. What is the y-coordinate of the y-intercept?

Answer 1

Take 2 points

• (0,4)
• (3,0)

Slope:-

`\\ \sf\hookrightarrow m=(0-4)/(3-0)=(-4)/(3)`

Now

for y intercept

• Put x=0

`\\ \sf\hookrightarrow y=4`

Answer 2

1) -4/3 2) ( 0 , 4)

Explanation:

1)

taking two coordinates the line is touching ( 0 , 4) , ( 3 ,0)

slope of the line:
`(y2-y1)/(x2-x1)`

:
`(0-4)/(3-0)`

:
`(-4)/(3)`

-4/3 is the slope of the line.

2)

Here the y intercept of is at 4 so the coordinates will be ( 0 , 4)

Extra's:

equation of line : mx + b ...where m is slope and b is y intercept

Here equation of line : y = -4x/3 + 4
