A line is defined by the equation y=2/3x-8. The line passes through a point whose y- coordinate is 0. What is the x-coordinates of this point?

12

Step-by-step explanation:

Equation of the line:

              y = - 8 ;

In slope intercept format, the equation of a line is :

          y = mx + c

If the y-coordinate is 0;

          0 =   - 8

Add 8 to both sides;

        8 =  

        24 = 2x

         x = 12

The x coordinate when y= 0 is 12.

answer: its the third option.

step-by-step explanation:

i just took the test.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
