Write the point-slope form of an equation of the line that is perpendicular to y=-2x-5 and has the same y-intercept as 2x+y=5.

Question

So, I can't figure out what the point-slope form is but I can find the slope-intercept form which is y=1/2x+5 and I hope that's correct. I only remember how to find the point-slope form if I have a point, but I don't have a point here, and now I'm just confused.

Thank you for whoever is going to help me with this question.

Answer 1

a perpendicular line has a negative inverse slope = 1/2

y intercept is 5

y=x/2 +5 is the perpendicular line with y intercept 5

the y intercept is a point (0,5)

You did it correctly.
