Question

Please help I don't know how to solve also can you explain​

Answer 1

Answer:

Perpendicular: 4, Parallel: -1/4

Step-by-step explanation:

The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.

First write the equation of the line in slope-intercept form

-x-4y=7

-4y=x+7

y=-(1/4)x-7/4;

The slope to the line is -1/4; Now find the slope of the perpendicular line;

-(-1/4)^-1 = 4

4

The slope of a line parallel to a line is the same as the given slope;

when we calculated the given slope, it was -1/4

The slope of the line parallel to this line is also -1/4

-1/4
