A. 2
B. -2
C. 5
D. -5
4. What is the y-intercept of the line? y=5x+2
A. 2
B. -2
C. 5
D. -5
5. What is the first step to graphing a line using Slope-Intercept form?
A. Plot the y-intercept
B. Find a second point by counting the slope as rise over run.
C. Draw a line between the two points

Answer 1

In general, the slope of y = mx+b is m. The y-intercept is b.

Example:

y = 4x + 20

slope: 4 or 4/1

y-intercept: 20, which is the point (0, 20)

Answer 2

this is because in this example, m = 4 and b = 20

Answer 3

sorry im a little lost

Answer 4

does my example make sense?

Answer 5

in y = 4x + 20, compare that to y = mx+b to see that m = 4 and b = 20

so

slope is 4 or 4/1

y-intercept is 20, which is the point (0, 20)

Answer 6

not really sorry this is all confusing to me

Answer 7
