Determine which of the lines, if any, are parallel. Explain. Line a passes through (-1, - 2) and (1,0).
Line b passes through (4, 2) and (2, – 2).
Line c passes through (0, 2) and (-1,1).
The slopes are

None are parallel since no slopes are equal

Step-by-step explanation:

Slope Equation:

Step 1:  Find the slope of the first line

Line a passes through (-1, -2) and (1, 0).

Step 2:  Find the slope of the second line

Line b passes through (4, 2) and (2, -2).

Step 3:  Find the slope of the third line.

Line c passes through (0, 2) and (-1, 1).

 None are parallel since no slopes are equal

question: how many people can she serve?
