What is the formula for slope 8th grade?
8.4A use similar right triangles to develop an understanding that slope, m, given as the rate comparing the change in y-values to the change in x-values, (y2 – y1)/(x2 – x1), is the same for any two points (x1, y1) and (x2, y2) on the same line.
What is the slope of an 8 grade?

What is y-intercept in 8th grade math?
The y-intercept is the y-coordinate of the point where the graph crosses the y-axis. In slope-intercept form (y = mx + b), the y-intercept is b.
How do you find the intercept form?
The intercept form of the equation of a line is x/a + y/b = 1. This is one of the important forms of equations of a line. Also, the sign of the intercepts in this equation help us to know the location of the line with respect to the coordinate axes.
How do you find slope-intercept form from points?
Steps to find the equation of a line from two points:
- Find the slope using the slope formula.
- Use the slope and one of the points to solve for the y-intercept (b).
- Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
