Answer:
y = x+
Step-by-step explanation:
Okay, the first thing to do here is calculate something known as the "slope".
We know two points are ( 1 , 5 ) and ( − 2 , 3 )
The slope is represented by "m" in the standard form: y = mx+b
The slope is also known as the rise over the run, y2-y1/x2-x1 = =
=> the standard form: y = x+b
Now we have to use the slope, and resubstitute another point to get b
5 = (1) + b
<=> b= 5- =
So the equation that model the line is: y = x+
