SOLUTION: The line: y=0.15x+0.79 and 0.11x-y=-0.85 Are the lines intersectiong, parallel,or perpendicular?

Question 395359: The line: y=0.15x+0.79 and 0.11x-y=-0.85
Are the lines intersectiong, parallel,or perpendicular?

Solve for y in 0.11x-y=-0.85 to get y = 0.11x+0.85

So we can see the slope of y = 0.11x+0.85 is 0.11

The slope of y=0.15x+0.79 is 0.15

Since this is NOT equal to 0.11, this means that the two lines are NOT parallel.

Also, because the two slopes both have the same sign (ie both are positive), they are also NOT perpendicular.

So the two lines are intersecting lines.
