Answer:

y= 2x -2

Explanation:

Slope-intercept form

y= mx +c, where m is the slope and c is they y-intercept


\textcolor{violet}{\text{\textcircled{1} Find the slope}}


\boxed{ slope = (y _(1) - y_2 )/(x_1 - x_2) }


slope = (0 - ( - 2))/(1 - 0)


slope = (0 + 2)/(1)

slope= 2


\textcolor{violet}{\text{\textcircled{2} \text{Substitute value of slope into m}}}

y= 2x +c


\textcolor{violet}{\text{\textcircled{3} Find c}}

Given that the y-intercept occurs at (0, -2), c= -2.


\textcolor{violet}{\text{\textcircled{4} Substitute the value of c into the equation}}

y= 2x -2
