A)
slop intercept form is y=mx+b
To find m, it is (y2-y1)/(x2-x1) or (-8-7)/(2-(-1)) which then = -5
To find b, the y-intercept choose one of the points and solve for b using:
y=x(slope)+b
7= -1( -5)+b
7= 5+b
2=b (subtract 5 on both sides)
I hope this helped!
They should still be 280 miles apart on the map i belive.
Question 1: The measure of the radius is the height h of the parallelogram.
Answer: h = r = 9 cm
Question 2: The measure of the distance across the base is the beast approximate base of the parallelogram.
Answer: b = 28.5 cm
Question 3: Calculate 3 times the radius.
Answer: 3 x radius (r) = 3 x 9 = 27 cm
Question 4: What is the mathematical difference between b and 3r? Calculate the absolute value of the two values.
Answer: Ib - 3rI = 28.5 - 3(9) = 28.5 - 27 = 1.5 cm
Question 5: Calculate the area of the parallelogram.
Answer: A = 3r² = 3(9) = 3(81) = 243 cm²
Question 6: Calculate the area of the circle.
Answer: A = πr² = (3.14)(9)² = (3.14)(81) = 254.34 cm²
