Answer:

y=2x-8

Explanation:

To write the equation in slope intercept form y=mx+b you need a slope and the y-intercept. We will calculate the slope and then substitute it and a point into the point slope form . Simplifying this form y-y1=m (x-x1) will result in slope intercept form.

Calculate the slope by subtracting the y values and x values of the points.

m= 6-0/7-4= 6/3=2

The slope is 2. Choose one point to use the slope with in the point slope form. Then substitute and simplify.

y-0=2(x-4)

y=2x-8
