Find the equation of a line that intersects with y=2x-1 on the y-axis and is parallel to y=-x.
Please explain.

Respuesta :

First you multiply2x1 which is 2so now you know that y=2 right then you multiply 2 x 3=6 6=x for the last you wright YxX = 2 x 6=12.Hope I helped) this is your answer

The equation of the required line is: y=-x-1.

y=2x-1 is in slope intercept form. So the y-intercept = -1.

Given that the line intersects with y=2x-1 on the y-axis. It means the required line also has y-intercpt =b= -1.

Given that: The line is parallel to y=-x.

The slope of y=-x is -1. By comparing with y=mx+b.

Since the lines are parallel. So the required line will also have slope = m= -1.

So the equation of the required line is: y=mx+b or y = -1x + (-1) or y=-x-1.
