Answer:
y=2x-3
Step-by-step explanation:
Slope intercept form : y=mx+b
where m is the slope, and b is the y-intercept
For slope intercept form, the only values that we need to find is m and b, so we just need to plug in 2 for the slope and the ordered pair for x and y to find b.
[tex]y=mx+b\\y=2x+b\\-1=2(1)+b\\-1=2+b\\-2 -2\\-3=b\\\\answer: y=2x-3[/tex]
