Question

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

Answer 1

Answer:

$y=2x+4$

Step-by-step 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
