Question

find the equation of the line that satisfies the following conditions. write your answers in both slope intercept form and standard form.
1. passes though the points (-1,1), (6,-5)
2.passes though (3,5) and has a slope equal -3.
3. passes though (-2,-4) and parallel to the line 2x+3y=9.
4.passes though (-2,-4) and perpendicular to the line 3x+2y=-4
5. has y intercept y=2 and slope equal zero.
6. has x intercept x=3 and slope equal 3.
7. passes though (2,100) abd has an undefined slope.

Answer 1

You can get 1 & 2 by direct substitution \[y-y_{1}=\frac{ y_2 - y_1}{ x_2 - x_1 }(x-x_1)\]

Answer 2

oh! thx!

Answer 3

how about others?
