Determine whether the graphs of y=3x+5 and -y=-3x-13 are parallel, perpendicular, coincident, or none of these

Step-by-step explanation:

Given lines are

Since second equation is not in slope intercept form, let us change it to slope intercept form

We see that slope of the I line is 3 and slope of II line is also 3

Since slopes are equal, we see that the lines are parallel

NOte that two lines will be parallel or coincident if slopes are equal

These two lines have same slope, but not coincident since y intercepts are different as 5 and 13

So these two lines are parallel

Not coincident and not perpendicular

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis
