Answer:

y=2/3x-3

Step-by-step explanation:

The slope-intercept formula for a line is: y=mx+b.

If the y-intercept is (0, -3), that means that the y-intercept ("b") is -3.

Updated equation: y=mx-3.

Plug in the point that you were given.. (-9,-9).

-9=-9m-3.

Add 3 to both sides.

-6=-9m.

Divide by -9.

m=-6/-9 = 6/9 = 2/3

The slope ("m") equals 2/3.

y=2/3x-3 is your equation.

The equation of a line through given points is required.

The equation of the line is [tex]y=\dfrac{2}{3}x-3[/tex]

The points are

[tex](0,-3)[/tex]

[tex](-9,-9)[/tex]

Equation of a line is given by

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\Rightarrow y-(-3)=\dfrac{-9-(-3)}{-9-0}(x-0)\\\Rightarrow y+3=\dfrac{2}{3}x\\\Rightarrow y=\dfrac{2}{3}x-3[/tex]

The equation of the line is [tex]y=\dfrac{2}{3}x-3[/tex]
