Last one PLEAAASE HELP. I'm terrible in math Write the equation of the line in slope-intercept form with a slope of -5 and a y-intercept of -1.

Question

jim_thompson5910 · Answer

y = mx + b

y = -5x + b ... plug in the given slope m = -5

y = -5x + (-1) ... plug in the given y-intercept b = -1

y = -5x - 1

jim_thompson5910 · Answer

In general, y = mx + b describes any line with a slope of m and a y-intercept of b

anonymous · Answer

How do you get b?

anonymous · Answer

b is just the y-intercept

jim_thompson5910 · Answer

b is the y-intercept

jim_thompson5910 · Answer

in this case, the y-intercept is -1, so b = -1

anonymous · Answer

So x basically has no value?

jim_thompson5910 · Answer

don't worry about x right now

it takes on many values, but we don't know the value it takes on right now

anonymous · Answer

wouldn't the answer be y=-5x-1?

jim_thompson5910 · Answer

that's what I wrote

anonymous · Answer

okay... didn't see that..lol

jim_thompson5910 · Answer

lol that's fine

anonymous · Answer

Oh okay, I wish you wouldn't have done it for me. All you had to do was explain it.I kinda wanted to know how to do these lol But it's okay I am thankful for the help.

jim_thompson5910 · Answer

oh sry about that

jim_thompson5910 · Answer

ok here's another: 

what's the equation of the line with a slope of 1/2 and a y-intercept of 10

anonymous · Answer

y=mx+b   y=1/2x+10
                y=1/2 + 10                       
did I do it right?

jim_thompson5910 · Answer

where did your x go?

jim_thompson5910 · Answer

it should be $$\Large y = \frac{1}{2}x + 10$$

jim_thompson5910 · Answer

assuming it's a typo, you got it right

anonymous · Answer

im sorry i meant to put it in there. but thank you! i actually understand something in math!

jim_thompson5910 · Answer

yay that's great, and no worries happens to me all the time
