Answer:
the slope is -2/1
Step-by-step explanation:
(10,-9) and (3,5)
y2-y1/ x2-x1
5-(-9)/3-10
14/-7
If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)
x + 21 = 2x - 40 Add 40 to both sides
x + 61 = 2x Subtract x from both sides
61 = x Switch the sides to make it easier to read
x = 61
I don't know how to explain but the answer is 2.4.
