Directions: Graph each equation by using the y-intercept and slope( make sure too show your work)
vova2212 [387]

Given:

The equation of a linear function is:

y=-\dfrac{2}{3}x-1

To find:

The y-intercept and slope of the given equation, then draw the graph of the equation.

Solution:

Slope intercept form of a line is:

y=mx+b             ...(i)

Where, m is the slope and b is the y-intercept

We have,

y=-\dfrac{2}{3}x-1        ...(ii)

On comparing (i) and (ii), we get

m=-\dfrac{2}{3}

b=-1

Therefore, the y-intercept is -1 and the slope of the line is -\dfrac{2}{3}.

It means the graph intersect the y-axis at point (0,-1) and having slope -\dfrac{2}{3}. So, the graph of the equation is shown below.
