Question

Finding the Equation of a Line from a Graph and a Table

plz help me

Answer 1

slope (m)= 1/2

y-intercept: (0, -1)

equation: y=
`(1)/(2)`x-1

Explanation:

slope is
`(rise)/(run\\)`=
`(1)/(2)`

y-intercept is where the line crosses the vertical axis (y-axis) so its (0, -1)

using point slope form:

y-y1=m(x-x1)

y-(-1)=1/2(x-0)

y+1=1/2x

y=
`(1)/(2)`x-1
