It is 3 to 4
you find the GCF of 24 and 32 which is 8. then divide 24 and 32 by 8 to find the ratio
#4
Examine the relationship between y and x, waiting until later to examine the y-intercept. For example: If we look at B, and mult. x = 2 by 0.55, we get 1.10, which is not even close to the y = 6.5 given in the table. If, however, we mult. 2 by 3.55, we get 7.10, which is not the same as the y = 6.5 given in the table, but is much closer than 1.10.
Also note that all y values in the table are positive, so a negative slope would be inappropriate. That eliminates choices A and D.
Focus now on the remaining choices B and C. Again, let x= 2 and determine the associated y value. Which y value is closer to the table's 6.5?
B: 0.55(2) + 3.55 = 4.65 (relatively far away from the table's 6.5)
C: 3.55(2) - 0.55 = 6.55 (very close to the table's 6.5)
C is the correct answer.
Domain is {-2,-1,0,1,2} and range is {2,3,6}
