Which line has a slope of 1, and which has a slope of 2?
aleksley [76]

Answer:

Line "L" has the slope of 1 and line "K" has the slope of 2.

In order to graph a line with the slope of \frac{1}{3} think of the numerator as the "rise" (how much you move up/down on the y-intercept) and the denominator as the "run" (how much you move to the side on the x-intercept)

Step-by-step explanation:

A slope of "1" is simply \frac{1}{1} so you rise up one and move to the right once. This clearly demonstrated on line "L".

A slope of "2" is \frac{2}{1} so you rise up two and move to the right once, as is demonstrated on line "K".

For the 2nd question, line "A" will have a slope of \frac{1}{3} therefore it will move up once and then to the side three times. It will look like the image attached to this answer.

I hope this helped! Feel free to ask questions if needed!
