Question

linear equation 3x+y=0 2x+y=-3.....so you add 3x+2x and get 5x then you will add y+y and 2 y correct then you have -3-0 which becomes 5x+2y=-3 then I am lost please help

Answer 1

wait, what's the question?

Answer 2

lol yeah you are back

Answer 3

linear equation by graphing
3x+y=0
2x+4=-3

Answer 4

you wanna change those equations from standard form to slope-intercept form

Answer 5

dont you add the 3x +2x=5x
then the y+y=2y
so 5x+2y=-3 right
that 4 above should be a y

Answer 6

um, no. you don't do that lol. you have to change them from standard to slope-intercept form

Answer 7

then you can graph them easily

Answer 8

so that is the y2-y1 and the x2-x1 run and rise ordeal

Answer 9

no. that was the slope formula

Answer 10

standard form: ax + by = c
slope-intercept form: y = mx + b

the equations of the lines are currently in standard form, so you have to change them into slope-intercept

Answer 11

i'll do the first equation for you
