What is the equation?
Nana76 [90]

Answer:

y=-2+4

Step-by-step explanation:

we know the y intercept is four, so we can plug that into y=mx+b

so far we know y=mx+4

and the equation for finding slope is \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

so let's find two points on the graph

let's make it easy on ourselves and use the points laid out for us

(0,4) and (2,0)

\frac{0-4}{2-0}

solving that would come out to be \frac{-4}{2}

simplified, that would be -2

now that we know the slope, we can put them into slope-intercept form

y=-2+4

4) -4y= -x + 4<br> 6) y + 3x = 3
wel

Answer:

x=16/13

y= -9/13

Step-by-step explanation:

A:         -4y=-x+4

B:          y+3x=3

4B:       4y+12x=12

A+4B:   12x= -x+16

----->    13x=16

               x=16/13

-4y= -16/13+4

4y=16/13-4

y=4/13-1= -9/13
