money >= jeans + tshirts
65 >= 29 + 9* number of shirts
subtract 29 from each side
36> =9 *number of shirts
divide by 9 on each side
4 > =number of shirts
He can buy 4 or less shirts
Choice A
Answer:
The line plot should have 6 dots on the 12 tick mark, 2 on 13, and 6 on 16.
Let
A(4,5) B(8,7) C(12,9) D(16,11)
1) Find the slope AB
m=(y2-y1)/(x2-x1)
m=(7-5)/(8-4)=0.5
2) Find the slope BC
m=(9-7)/(12-8)=0.5
3) Find the slope CD
m=(11-9)/(16-12)=0.5
The points represent a linear function
so
<u>Find the equation of the line with m=0.5 and the point A(4,5)</u>
we know that
y-y1=m*(x-x1)
y-5=0.5*(x-4)
y=0.5*x-2+5
y=0.5*x+3
therefore
<u>the answer is</u>
The equation is equal to y=0.5*x+3
