Please help 1 Find parametric equations for the line of slop

Please help!

1) Find parametric equations for the line of slope 3 that passes through the point (9, 7). (Use t as your parametrized variable. Enter your answers as a comma-separated list.)

Solution

The equation of line with slope m and passes through (x0,y0) is (y-y0)=m*(x-x0).

So here m=3 and point is (9,7) so equation of line is

(Y-7)=3*(X-9) so line is y=3x-20.

Now the parametric form let x=t then y=3t-20

Equation of line in parametric form x=t; y= 3t-20 where t is a

Parametrized variable
