Question 781092: How do I find the slope and y intercept of the equation x-3y+6=0?
Answer by wilft1(217) (Show Source): You can put this solution on YOUR website!
easiest way to find the intercept for either x or y is to simply make it a zero in the equation, example
x-3(0)+6=0 then just solve for x, which in this case will be x = 6
so you have your first intercept, (6,0)
lets find the x intercept, remember, replacing x with zero
0-3y+6=0 in this case, y = 2
we now have our y intercept (0,2)
now, to find our slope, remember slope intercept form y-mx+b where m represents the slope
m = y2-y1
,,,,,,-----
,,,,,,x2-x1
cant really use our intercepts for this because you would be subtracting 0 from 0, i just tried, so i'll use 2 other points that i plotted out(6,4)and(9,5)
,,,5 - 4,,,,,, 1
m=------ = --
,,,9 - 6,,,,,, 3
theres your slope, 1/3
for every 3 you go right, you go up 1
