Use the graph to find the slope and y-intercept to write the equation in slope-intercept form.

On a coordinate plane, a line goes through points (negative 2, 0) and (0, negative 1).

The graph shown is y =
x +

Answer:


m = -(1)/(2)


y\ intercept = -1


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

Explanation:

Given


(x_1,y_1) = (-2,0)


(x_2,y_2) = (0,-1)

Required

Determine the slope and y intercept from graph

To calculate the slope, we have:


m = (y_2 - y_1)/(x_2 - x_1)


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


m = (-1)/(0 +2)


m = -(1)/(2)

The y intercept is when
x = 0

So,


y\ intercept = -1

The equation is then calculated using:


y = m(x - x_1) + y_1

This gives


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


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


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


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


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