Can you help me to solve this

Question

A line has equation y=5x+4.

this line has slope:

any line parallel to this line has slope:

any line perpendicular to this line has slope:

Answer 1

Your equation is in the form y = mx + b, where m is the slope, and b is the y-intercept (where x = 0)

Any parallel line will have the same slope

A perpendicular line will have a slope that is the negative inverse

---eg, if a line has a slope of 2, the perpendicular line has a slope of -1/2
