Question

Help me out please!!!!!!

Answer 1

Explanation:

We need 2 things in order to write slope-intercept equations: the slope, and the y-intercept. Remember that the form is
`y=mx+b`, where
`m` is slope and
`b` is y-intercept. All of the lines show the y-intercept, but not the slope. We can calculate slope using two points on the line and the slope equation,
`m=(y2-y1)/(x2-x1)`.

1. Two points: (1,-3) and (0,4)

`m=(4-(-3))/(0-1)=(7)/(-1)=-7`

So the equation would be:
`y=-7x+4`

2. Points: (-1,-2) and (0,1)

`m=(1-(-2))/(0-(-1))=(3)/(1)=3`

Equation:
`y=3x+1`

3. Points: (0,5) and (-2,4)

`m=(4-5)/(-2-0)=(-1)/(-2) =(1)/(2)`

Equation:
`y=(1)/(2)x+5`

4. Points: (0,-2) and (-4,1)

`m=(1-(-2))/(-4-0)=(3)/(-4)=-(3)/(4)`

Equation:
`y=-(3)/(4)x-2`

Hope this helps!
