Question

Identify the equation that describes the line in slope-intercept form. slope = 2 , point (- 1, 2) is on the line

Answer 1

`y=2x+4`

Explanation:

• Given a slope and a point on the line, you can use point slope form and then rearrage your terms into slope-intercept form

• SLOPE-INTERCEPT FORM:
  `y=mx+b`, where "m" is your slope and "b" is your y-intercept
• POINT-SLOPE FORM:
  `(y-y_(1)) =m(x-x_(1))`, where
  `y_(1)` represents the y-coordinate of your point,
  `x_(1)` represents the x-coordinate of your point, and
  `m` represents the slope

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

• Point-slope form

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

`y-2=2x+2`

`y=2x+4`

• Slope-intercept form
