Question

What is the equation of the line shown in this graph

Answer 1

Answer: y = c

Explanation:

(x1,y1). = (-2,-3)

(x2,y2) = (3,-3)

equation of a straight line (y = mx + c)

Since m= (y2-y1) / (x2-x1)

= {-3-(-3)} / {3-(-3)}

=0/5

m= 0

Y = mx + c, putting 0 for m

Y = (0)x + c

Y =0+c

Y = c

Answer 2

y = - 3

Explanation:

This is a horizontal line parallel to the x- axis as indicated by the 2 coordinate points the line passes through. That is both have the same y- coordinate , - 3

The equation of a horizontal line is

y = c

Where c is the value of the y- coordinates the line passes through, thus

y = - 3 ← equation of line
