Question

Enter an equation in point-slope form for the line.(7,6) and (8,3) is on the line.

Answer 1

First, we will calculate the slope of the line

`m=(3-6)/(8-7)`
`m=(3)/(1)\rightarrow m=-3`

Now let's calculate the y-axis crossing

`b=y-mx`
`b=6+3\cdot7`
`b=6+21`
`b=27`

The equation would be: y = 3x - 15

`b=y-mx`
`b=3+3\cdot8`
`b=27`
`y=-3x+27`
