y= 3/7 x+11
-3x + 7y = 13
Part A: Convert the second equation to slope-intercept form. Show your work!
-3x + 7y = 13
Add 3x to both sides
7y = 3x + 13
Divide both sides by 7
y = 3/7 x + 13/7
Answer: Slope intercept form: y = 3/7 x + 13/7
Part B: Determine whether or not the graphs of the lines are parallel. Explain how you know.
First equation: y= 3/7 x+11 , this equation has slope equal 3/7
Second equation: y = 3/7 x + 13/7, this equation also has slope equal 3/7
Slopes are the same so both graphs of the lines are parallel.
