Question

HELPPP PLEASE

Use point-slope form, y - y, = m(x - x1), to find the linear equation of a line that
passes through the points (3,-1) and (1, 1),

Answer 1

`y=1`

Explanation:

step 1

Find the slope of the line

The formula to calculate the slope between two points is equal to

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

we have

`(3,1),(1,1)`

substitute

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

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

`m=0`

Is a horizontal line (parallel to the x-axis)

step 2

Find the equation in point slope form

`y-y1=m(x-x1)`

we have

`m=0`

`(x1,y1)=(1,1)`

substitute

`y-1=(0)(x-1)`

`y-1=0`

`y=1`
