Answer:
slope = 6
y-intercept = -5
Step-by-step explanation:
The equation is in slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept
Let's find the slope:
The slope is the number being multiplied by x.
y = mx + b
y = 6x - 5
Therefore, the slope is 6.
Let's find the y-intercept:
The y-intercept is the last number in the equation.
y = mx + b
y = 6x -5
Therefore, the y-intercept is -5.
Answer:
If the amount spent on books per month by all her the classmates is leveled, that amount would be $30.
Step-by-step explanation:
The mean is the average amount calculated by finding the sum of a certain group of numbers, then dividing it.
This can be described as "leveling" the amount, since it is the total average.
So, the mean of $30 in this situation means that the average amount that her classmates spend on books is $30.
The correct answer is that If the amount spent on books per month by all her the classmates is leveled, that amount would be $30.
