Find the equation whose graph is shown below. Write your answer in standard form.
(Standard form is , where is positive, and , , and are integers with greatest common divisor 1.)
I can tell you copied the last sentence. I know what standard form is though so...
Standard form is Ax+By=y intercept
The slope is -2
so our first equation is 2x+y=the y intercept
The y intercept in this equation is -3
So the equation is 2x+y=-3
Yay!
Edit:
NVM ON MY NVM IM WRONG AS ALWAYS
I'M BLIND LOL
Find two convenient points -2,1 And 0,-3 Calculate slope as ( y1-y2)/(x1-x2) = - 2
y = -2x + b Sub in one point to calc b
1 = -2(-2) + b b= -3
y= -2x -3
Y = Mx + b is a standard form of a line
The poster should be able to do this:
... Y= -2x - 3 Or Y+ 2x = -3
uhm actually the y-intercept is –3. not –4. Better push those glasses back down.
.
isnt that what he just said in his answer "the y intercept in this equation is -3"
EP's answer was also "The y intercept in the equation is -3"...
so what are you talking about
