Answer:
k = 6
Step-by-step explanation:
Step 1: Find slope <em>m</em>
m = (4 - 8)/(-10 - 6)
m = -4/-16
m = 1/4
y = 1/4x + b
Step 2: Find <em>b</em>
4 = 1/4(-10) + b
4 = -5/2 + b
b = 13/2
Step 3: Rewrite equation
y = 1/4x + 13/2
Step 4: Find <em>k</em>
y = 1/4(-2) + 13/2
y = -1/2 + 13/2
y = 12/2
y = 6
Answer:
m=-4
Step-by-step explanation:
M-9=-13
+9 +9
M=-4
Hope it helps :)
Let the unknown number be 
.
Then the opposite of this unknown number will be 
.
It is given to us in the question that when this unknown number, is increased by 9, or in other words when 9 is added to this unknown number, , then this becomes 5 times it's opposite, which is .
Thus, from the given condition in the question, the equation we get is as:
We will solve this by isolating as:
Thus the required number is -1.5
