What line includes the ordered pairs (1,3) and (0,1)?
..
The standard form of the equation to use: y=mx+b, with m=slope and b=y-intercept,
slope,m=change in y/change in x or rise/run
m=3-1/1-0=2/1=2
y=2x+b
To find b, use x and y in one of the points and solve for b
3=2*1+b
3=2+b
b=1
ans:
Equation of line:
y=2x+1
In the graph below note the slope, y-intercept and the 2 given points on the line.
