Use the points (1998,13.60) and (2003,19.00) to write the slope intercept form

y=1.08x-2144.24

Step-by-step explanation:

find the slope: m=(19.00-13.60)/(2003-1998)=1.08

so we have y=1.08x +b

next, use the point (2003, 19.00) to find b:

19.00=1.08*2003 +b =>b=-2144.24

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
