What is the equation of a line with a slope of –2 that passes through the point (6, 8)? 2x + y = 20 y – 2x = 4 y – 2x = 20 2x + y = 4

Y= -2x=20 All you have to do is use the equation y=mx+b. For the y you plug in 8, the m= -2, plug in x which is 6 and since you're finding the b you just put +b at the end. So it looks like this, 8=-2(6)+b.

Now you solve it... Just drop the 8 and multiply -2 x 6 which ='s -12. Then you just drop the +b so the equation now looks like this, 8=-12+b. You'll notice there's a -12 so you just simply add 12 to both sides and your answer should be 20=b.

Knowing m=-2, your answer should be y= -2x+20.

The answer would be quadratic trinomial
