Hi  

What is the equation of each line slope-intercept form?

a. parallel to y=3x+1 through (4,-1)  |Equal Slopes.

y = 3x + b

-1 = 3(4) + b,  b = -13

y = 3x - 13   is the equation of the line in  slope-intercept form

b. perpendicular to y=3x-4   | perpendicular line:    m = -1/3

with the same y-intercept as -x+5y=10 0r 

y = mx + b

y = (-1/3)x + 2  is the equation of the line in  slope-intercept form 

Wish You the Best in your Studies.

The part  a)  in post by  @ewatrrr should be corrected.





The correct/corrected equation is    y = 3x - 13.

OK, it is just DONE.
