Question

using standard form, write the equation of the line through (-2, 5) and parallel to y=-2x+5

using point slope form, write the equation of the line through (1,-5) and perpendicular to -3x+2y=12

Answer 1

(-2, 5) = (x,y)
substitute the x and y into

y=-2x+b they give you x and y and all parallel lines have same slope so ..


then you will solve for b

Answer 2

remember standard form is

Ax + By = C

start this problem then i can help you with the next but should only post one at a time.

Answer 3

okay thanks

Answer 4

i got 8, did i do that right?:o
