Answer:
y=5
Step-by-step explanation:
The equation of a line can be written as y − y 0 = m ⋅ ( x − x 0 ) where ( x 0 , y 0 ) is any point that lies on the line. The gradient, m , of the line can be found using any two non-identical points that lie on the line. m = y 2 − y 1 x 2 − x 1 = 5 − 5 − 3 − 0 = 0 A gradient of zero indicates that the line is horizontal. The equation of the line can thus be simplified to y = y 0 In this case, both points have a y coordinate of 5. The equation of this line is therefore y = 5 .
