how do write an equation of a line that passes through (8,4) and has an y- intercept of 6?

Apr 28th, 2015

If the line has a y-intercept of 6, that is the point (0,6);  that along with the other point (8,4), allows us to find the slope using the slope formula:

(4-6)/(8-0) = -2/8 = -1/4

So now we can put it in slope-intercept form:

y = -1/4 x + 6

Hope that helps.
