Question 64959: How do I find the slope of a line with just an equation? ex: 3x+y=7 Found 2 solutions by tutorcecilia, josmiceli:Answer by tutorcecilia(2152) (Show Source):
You can put this solution on YOUR website!
y=mx+b [use the slope-intercept form as a model]
y=any y value on the line
m=the slope of the line
x=any corresponding x value on the line
b=the y-intercept (0,b)]
.
3x+y=7 [re-write the equation in the slope-intercept form by solving for y]
y=-3x+7 [match-up the model with this equation]
y=mx+b
