Answer:
m = -30
m = slope
Step-by-step explanation:
(1,57) and (2,27)
(x1,y1) and (x2,y2)
y2 - y1. 27 - 57
---------- =. ---------- =. -30/1 = -30
x2-x1. 2 - 1
Answer: 55.56
Step-by-step explanation:
Let the unknown number be k
(45 x k) / 100 = 25
45k/100 = 25
multiply both sides by 100
45k = 25 x 100
45k = 2500
divide both sides by 45
k = 2500/45
k = 55.56
