Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= - 
The y- intercept is where the line crosses the y- axis
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
(b)
y = - x + 3 ← equation of line
2 ( k-5) 13 you don't need two k-5 you can simplify it so you just know to do it twice
Answer:
2persent
Step-by-step explanation:
because there are 10 10 in 100
multiply 5 times 21 then 4 times 15 and then add them together
Sounds as tho' something's missing here. What is "the average" You haven't given it.
If "the average" were 5, then 1 is 4 units below the average, 4 is 1 unit below the average, and 6 is 1 unit above the average.
Check the original problem. Isn't the average given there?
