Question

Please help!!! find the equation of the line containing the given points (3,4) and (9,9)

Answer 1

@dawn354215 equation of a line passing through two points (x1, y1) and (x2, y2) is given as
\[\frac{y-y2}{x-x2}=\frac{y2-y1}{x2-x1}\]
Here (x1, y1)= (3,4)
and (x2, y2) =(9, 9)
Can you try now?

Answer 2

Find the gradient first using change in Y/change in X. As explained above then use one of the given points to find the equation.

\[y-4\div x-3\] = Gradient and cross multiply
