Step-by-step explanation:
2) Slope can be written as rise over run:
- rise: add to the y-value
- run: add to the x-value
3) Slope formula is:
4) Average rate of change is the slope of the given interval:
a) when x = 0, y = 0 and when x = 1, y = -3
b) when x = -2, y = 0 and when x = -1, y = 3
c) when x = 0, y = 0 and when x = 2, y = 0
When you're graphing a line in slope-intercept form (y = mx + b), your first step is to look at b, which is your y-intercept. The y-intercept is where your line touches the y-axis.
Slope-intercept form is y = mx + b, but for y = -5x doesn't have a b, so you have to add one. You can do this by adding + 0 to the end, since it won't change your equation.
y = -5x + 0
b = y-intercept = 0
m = slope = -5
So, your line will start at 0 on the y-intercept, which will be at the origin point (0,0).
Your slope is -5, or , so you'll go down 5 and then to the right 1.
A few points on your line should be (0,0), (1,-5), and (-1,5).
