Through (2,0) slope = -5/3 write the slope intercept of the equation
babunello [35]

For this case we have that the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

In this case we have the following data:

m = - \frac {5} {3}\\(x, y) :( 2,0)

Then, the equation is of the form:

y = - \frac {5} {3} x + b

We find "b" replacing the point:

0 = - \frac {5} {3} (2) + b\\0 = - \frac {10} {3}\\b = \frac {10} {3}

Thus, the equation is:

y = - \frac {5} {3} x + \frac {10} {3}

Answer:

y = - \frac {5} {3} x + \frac {10} {3}
