Question 49608
well there are two ways to do this problem either use the point-slope forumla or the slope intercept formula.<br>

using the point-slope formula we get<br>

y-y1=m(x-x1)<br>

y1 = 4
m = 2
x1 = 6<br>

y-4=2(x-6)
y = 2x-12+4
y = 2x-8<br>

using the slope intercept formula we get<br>

y = mx+b<br>

y = 4
m = 2
x = 6<br>

4 = 2(6)+b
4 = 12+b
-8 = b<br>

y = 2x-8<br>

either way you get the same answer y=2x-8 or if you want it in standard form its 2x-y=8
