Question

write an equation for this graph for all lines using the equation (y = mx + b)

Answer 1

Answer:

0

Step-by-step explanation:

(y = mx + b)  just means  y = slope multiplied by constant rate of change + y - intecept.

Y - intercept is the starting ammount or the ammount paired with 0. (0,...)

You can find slop by using the equation y1 - y2 divided by x1 - x2.

Then lastly x in the number that in running along the middle line.

Answer 2

Take any point of the line. I'm going to use (0,2).

(x,y)=(0,2). Therefore x=0 and y=2.

Next, b is the y intercept, and in my explanation (0,2) is the y intercept. Therefore b=2.

Now substitute variables for numbers that you know.

2=0m+2

Therefore m=1.

Now finally substitute m and b into your equation.

So your equation is:

y=x+2
