Answer: Slope = -2.667/2.000 = -1.333

x-intercept = 5/4 = 1.25000

y-intercept = 5/3 = 1.66667

Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

HELP ME Solve. h ÷ 4 = 9

Umnica [9.8K]

Isolate the h. Do the opposite of the sign given - Because of equal sign, what you do to one side you do to the other

h/4 = 9
h/4(4) = 9(4)
h = 9(4)
h = 36

36 is your answer for "h"

hope this helps
