What is the slope of the equation (y - 3) = 5(x - 1)?
5
What is the slope of a vertical line ?
Underfined
What is the rise and run from this slope? 5/2
Up 5 over 2 to the right.
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 point of the equation (y - 3) = 5(x - 1)?
(1, 3)
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).
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.
What is the slope of the equation (y - 9) = -3(x + 1)?
-3
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

8
What is the slope of the equation (y - 3) = 2/3(x - 1)?
2/3
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.
