How do you graph #y=3x+4# using the slope and intercept?
1 Answer
See detailed explanation.
Explanation:
I'm sure that you know the formula for slope-intercept form but if you don't, here it is:
Note: m = slope; b = y-intercept
Now correlating this with the given equation,
m(slope) = 3, and b(y-intercept) = 4.
Since we know the y-intercept is 4, we get the point
With a point and the slope, we can figure out the next points.
For instance, since the slope is
So the next point after the y-intercept would be
To get a previous point, the point will be
So the point before the y-intercept would be
