While determining the slope of a line that goes through the points (6,5) and (3,7), Gloria figured out that Δy=−2 and Δx=3 without graphing. a. Explain how Gloria could figure out the horizontal and vertical distances of the slope triangle without graphing.
b. What is the slope of the line?
c. Use Gloria’s method (without graphing) to calculate the slope of the line that goes through the points (4,15) and (2,11).
d. Use Gloria’s method to calculate the slope of the line that goes through the points (28,86) and (34,83).

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

i dont have an answer

step-by-step explanation:

answer:

a=9

step-by-step explanation: lmk if you need a explanation

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
