Question 1

Write the equation of the line that is parallel to the x-axis and contains point (2, 7).

Answer 1

PARALLEL LINES HAVE EQUAL GRADIENTS

THE GRADIENT IN THE X-AXIS IS EQUAL TO 0 SINCE THE THE Y VALUE FOR ANY X VALUES IS 0

`m = (0 - 0)/(x2 - x1) \\ m = 0`

This just means that the gradient for the line parallel to the given line is 0

I will use the technique of the General equation of a straight line. y=mx+c

`7 = (0)(2) + c \\ c = 7`

THE EQUATION IS

`y = 7`

ATTACHED IS THE SOLUTION.
