Question

A line that includes a point -7,0 has a slope of 20/7 what is the equation for slope intercept form

Answer 1

y=20/7x+20 i believe. used y-y1=20/7(x+7)

Answer 2

`y=(20)/(7)x+20`

Explanation:

Use the point slope form of the equation of a straight line:

`y-y_1=m(x-x_1)`

where m is the slope and
`(x_1, y_1)` is a point on the line

Substituting m = 20/7 and point (-7, 0) into the formula:

`\implies y-0=(20)/(7)(x+7)`

`\implies y=(20)/(7)x+20`

The y-intercept is (0, 20)
