Answer:
b. mode = 88, median = 77
Step-by-step explanation:
First, arrange all the numbers least to greatest.
53, 71, 75, 79, 88, 88
The mode is the number that occurs the most.
mode = 88
The median is the middle number. Since there is an even number of numbers, look at the two middle numbers 75 and 79. Add them together and divide by two (finding the average or mean of the numbers).
75 + 79 = 154
154/2 = 77
median = 77
Answer:
y = 5x + 3
Step-by-step explanation:
Slope-intercept form is y=mx+b (where m is the slope and b is the y-intercept)
First find the slope with (13-8)/(2-1) = 5
Plug the slope and one of the coordinates into the equation to find the y-intercept now:
13 = 5 * 2 + b
13 = 10 + b
b = 3 (y-intercept is 3)
Now, write final equation: y = 5x + 3
Yo get a perpendicular line you have to have the reciprocal of the slope, in this case the slope is -2/5 so the reciprocal is 5/2. You then plug the coordinates in for y and x with the slope you found to find b (or the y-intercept). The equation will be 2=-6(5/2)+b. Solve and b=17. The final equation is y=(5/2)x+17
