\[y=\frac{-3}{2}(-4)+1\]
\[y=\frac{-3}{2}(-2)+1\]
\[y=\frac{-3}{2}*6+1\]
OpenStudy (anonymous):
so my answers are( -4,-3),(-2,-1),&(6,7)
OpenStudy (anonymous):
Order of operations. You have to multiply -3/2 * x then add the one

Simple multiplications. Shouldn't need a calculator to get these ones.
OpenStudy (anonymous):
-3 * -4 over
2 * 1
OpenStudy (anonymous):
15/2
OpenStudy (anonymous):
close 3 times 4 is 12 not 15
so 12/2 which is 6 because 2 goes into 12 6 times.
OpenStudy (anonymous):
oh ok

y=6+1
so your first coordinate it (-4, 7)
OpenStudy (anonymous):
k
OpenStudy (anonymous):
the next one is 4 ?
OpenStudy (anonymous):
\[y=\frac{-3}{2}*\frac{-2}{1}+1\]
OpenStudy (anonymous):
Yes :]
