(9, 1) and (5, -7)
2
Identify the slope in this equation: y= 5x+2
5
Identify the y-intercept in this equation: y=-ax/b+c/b
c/b
What is the slope of a horizontal line?
0
Describe what rise over run:
A fraction consists of the rise (the change in y, going up or down) divided by the run (the change in x, going from left to the right).
(5, -2) and (7, 3)
5/2
Find the slope from this equation: 5x+2y=12
y=-5/2x+6
What is the definition for Y-intercept?
the point where the graph crosses the y -axis.
Why do the slope of a line stay constant?
This ratio is constant between any two points along a straight line, which means that the slope of a straight line is constant, too, no matter where it is measured along the line.
What is the run from this slope? 6/4

Define slope-intercept form:
the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
