Question

What is the equation of a horizontal line passing through the point (–7, 5)?

a. y = 5

b. y = –7

c. x = 5

d. x = –7

Answer 1

general equation of a line is:
y=ax +b
where a is the slope and b is the y-intercept

a horizontal line has slope=0
so here a=0
and the y-intercept is at (0,5)

so the equation is
y=5
