Question

What is the slope-intercept equation of this line

Answer 1

y = -3x + 4

Explanation:

Slope intercept form:

y = mx + b

Slope = y2 - y1/x2 - x1

-2 - 4/2-0 = slope

slope = -6/2 or -3

Equation:

y = -3x + 4

Answer 2

`y = 4x-3`

Explanation:

y-intercept = b = 4 (because x becomes zero here)

Now, Finding the slope:

Slope = m =
`(rise)/(run)`

Slope =
`(-2-4)/(2-0)`

Slope =
`(-6)/(2)`

Slope = -3

Now putting m and b in the slope intercept equation to get the required form:

=>
`y = mx+b`

=>
`y = 4x-3`
