Question

Determine if each pair of equations is parallel, perpendicular, or neither. Explain your reasoning.
y = x + 1 and y – x = 10

Answer 1

Same as the last. Add x on the second equation and get
\[\LARGE y=x+10\]

Answer 2

The slope for both are 1

Answer 3

The pair is parallel. They have the same slope which is 1 as luigi said.

Answer 4

so what work can I show???

Answer 5

simply take the formula to the form y=mx + c..where m and c are constants...m is the slope..for the lines to be parellel..both should have equal slopes..for perpendicular lines..the product of their slopes is -1..for any other the slope varies...
