Question

3x-y=-3, -15x+5y=15 parallel, coincident, or intersecting

Answer 1

Again. set y=mx+b. The more you practice the more you would understand it

Answer 2

I got x-y and x+5y

Answer 3

use algebra to set y on the left side only and the y intercept(b) and the slope(x) to the other side.

Answer 4

so in order to get y by itself, you move the x component to the other side. then if y has a coefficient next to it, divide both sides by the coefficient

Answer 5

Ok so I got -1/3y+1 and -1/3y-1 so intersecting

Answer 6

so for the fist one, 3x-y=-3.
1. I will add y to the other side (in order to get a positive value for y) and add 3 on both sides (to get y by itself)
2. I should get y=3x+3
there you are done. now do it for the other equation.

Answer 7

not quite. but yet. it is intersecting
