Put them in y= mx+b format. .
x+y=3 ---> y= -x+3
x-y=1 ---> y= x-1
The x's are your slope and the numbers are your y-intercept.
Hope it helps!

Isolate y in both the equations so
x+y=3 x-y=1
y=-x+3 y=x-1
your y-intercept is 3 y-intercept is -1
and slope is -1/1 slope is 1/1

The table shows the American League batting champions for the years 1999–2003. The sum of these five batting averages is 1.754.

fgiga [73]

The answer is A. .357 + .372 + .350 + .349 + x = 1.754; .326

x1 - average of 1999 Nomar Garciaparra Boston
x2 - average of 2000 Nomar Garciaparra Boston
x3 - average of 2001 Ichiro Suzuki Seattle
x4 - average of Manny Ramirez Boston
x - average of 2003 Bill Mueller Boston

The sum of these five batting averages is 1.754:
x1 + x2 + x3 + x4 + x = 1.754

From the table:
x1 = 0.357
x2 = 0.372
x3 = 0.350
x4 = 0.349
x = ?

0.357 + 0.372 + 0.350 + 0.349 + x = 1.754

1.428 + x = 1.754
x = 1.754 - 1.428
x = 0.326
