Question

How should I start to complete the equation????

Answer 1

Answer:

the answer may vary, seeing as you could use any of the coordinates, but in my case i got : y = -1/2 + 4

Step-by-step explanation:

formula : y = mx + b

to find your ' b ' you had to determine where the y intersects. in this case, it intersected on positive four.

to determine your m, you have to subtract two of the plotted coordinates from each other, in my case it was (-2,5) and (4,2)

y2 - y1

-----------

x2 - x1

2 - 5

--------

4 - ( -2 )

-3

-----

6

WHICH MEANS

m = -1/2

Answer 2

Answer:

Find the slope and the y-intercept

Step-by-step explanation:

To find slope, use the equation $\frac{y-y}{x-x}$. First, find two points on the line that are near each other and are whole numbers. Then you substitute the points into the equation.  So for example, if I had the points (0,0) and (1,2), the substitution would be:

$\frac{2-0}{1-0}$

To find the y-intercept, find where the line crosses over the y-axis. Then put in the y value.

If you do not know where to put slope and y-intercept:

y=mx+b

m=slope

b=y-intercept

slope= output/input
