Question

What is the equation of a line through the points (0, 9) and (3, 0)? because mc024-1.jpg; y = –3x + 9 because mc024-2.jpg; y = –3x + 3 because mc024-3.jpg; mc024-4.jpg because mc024-5.jpg; mc024-6.jpg

Answer 1

I cant see any of ur links...

(0,9),(3,0)
slope = (0 - 9) / (3 - 0) = -9/3 = -3

y = mx + b
slope(m) = -3
ur y int (b) is when x = 0....u already have the point (0,9)...so ur y int is 9

so ur equation is : y = -3x + 9....because u have a slope of -3 and a y int of 9
