Question

A line passes through the points (2,6) and (4,9) move an expression and a number

Answer 1

General equation of line is y=mx+c where m is the slope

Slope of line parallel to x-axis is m=0

So y=(0)x+c⟹y=c

(−4,6) lies on our required line y=c

⟹6=0(−4)+c

⟹c=6

Equation of the line is y=6
