Answer:
Step-by-step explanation:
If you try to find a line (linear) slope between two points (x,y) and (x',y')
the slope or ratio of change : m = difference of y / difference of x
or m= ( y - y') / (x - x')
In a linear equation like y = mx + b ... m is the slope
Answer:
Step-by-step explanation:R=14
Let x be the number of students in the class the
the number of students in the class when 1 in 4 are absent = x - 0.25x = 0.75x
After Jen returns there are x - 0.2x = 0.80x so we have the equation
0.75x + 1 = 0.80x
0.05x = 1
x = 1 / 0.05 = 20 Answer
So there are 20 students in the class.
No. students not here today = 0.80 * 20 = 16 Answer
We have to isolate b to be alone.
Soooo first we divide both sides by 6
-81 = b6
÷6 = ÷6 The right side cancels out and gets the b alone. While we solve the right side of the equal sign.
-81 ÷ 6 = -13.5
So this means we isolated b alone!
b = -13.5
Our final answer is..
b = -13.5
