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
