If p=50, then 50=4k-10
4k=60
k=15
Answer: the slope is 3 and the intercept is 0.
Step-by-step explanation:The trend line for the bivariate data shown in the scatter plot has the equation Y=3x
To determine the slope for a straight line (y=a*x+b)we take the two points that are shown and apply the following equation:
To determine the intercept we put the slope which we calculated into the equation for the point (2,6) and clear for b
To answer this you could do a couple things. 1. Actually calculate both tips and then subtract them. Here is the math ( assuming it is $60, not 60% that you mean). a. 0.15 x 60 = $9. b. 0.0825 x 2 x 60=$9.90. c. 9.90-9.00= $0.90 difference.
The other strategy would be to find the difference on the percents and then multiply by $60. a. 8.25%x2=16.5%-15%. Difference of 1.5%. b. 0.015 x $60=$0.90.
