First you have find the slope (a) in order to find the value of the y intercept (b).
To compute the slope, you simply have to find the difference of y coordinates and divide them by the difference of x coordinates:
a = (y2-y1)/(x2-x1)
a = (7-3)/(-2–0)
a = 4/-2
a = -2
To compute the y intercept denoted by b, we substitute the value of a with -2 in the formula and choose any point (x,y) and substitute their values in the formula as well. Like so:
I choose point A:
3 = (-2)(0) + b
3 = b
Answer
131ft^2
Step-by-step explanation:
I find area by basically taking the figure and making it into two figures and solving the area for the two then adding them up.
Answer:
y=15/2x+40
Step-by-step explanation:
The slope is 15/2, and the y-intercept is 40.
Sure where is the problem
To find the percentage of any number you divide your percentage by 100 to get a decimal. 14 ÷ 100 =0.14 then in this case you need to find the number you want to find 14% of . Each reindeer harness is 17.95 so 17.95 * 9 = 161.55 so now you take 161.55 and multiply it by the decimal to get the percentage of 161.55 which equals 22.617 so now add the tax and the cost of the reindeer harnesses and you got your answer :)
