To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
The slope of a line going through the point (1, 2) and the point (4, 3) is $$ \frac$$.
You can chose how large the numbers will be by adjusting the difficulty level.
The slope intercept form is probably the most frequently used way to express equation of a line.
But the slopes are the same fraction, rather than one being the flip (that is, the reciprocal) of the other, so these lines are not perpendicular, either.
Take note that the slope obtained would be the same no matter which two points on the line were selected to determine the rise and the run. How to find the slope of a line using the ratio of rise over run between any two points on the line?
While there are infinitely-many different literal equations, some kinds are more likely to be important, and sooner, than other.
Probably one of the most important classes of literal equations we often need to solve will be linear equations.
She was having a bit of trouble applying the slope formula, tried to calculate slope 3 times, and she came up with 3 different answers. You can practice solving this sort of problem as much as you would like with the slope problem generator below.
It will randomly generate numbers and ask for the slope of the line through those two points.
