Take the price of pears (£1.30 per kilogram) and multiply it by the amount of pears (7kg). You get 9.1 so now you take the total amount spent (£12.70) and subtract the 9.1 and you get 3.6 now that is the amount you spent on the apples. So take 3.6 and divide it by the amount of apples you got (2kg) you will get 1.8 and that is your overall answer.
Answer:
Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate.
Step-by-step explanation:
The unit rate is the change in y for a 1-unit change in x. Since the graph of a proportion will go through the origin, it is appropriate to look at the y-value for x = 1 (one unit from the origin).
___
The ratio of units up to units to the right is also the unit rate when the fraction is reduced to lowest terms. It is a "unit" rate when the denominator of the fraction is 1 unit.
Answer:
Step-by-step explanation:
Slope-intercept form is given as 
, where 
is slope and 
is the y-intercept.
To find the slope of a line that passes through two points 
and 
, use the slope formula:
Let:
The slope of the line that passes through these two points is:
Now substitute 
and any point to solve for :
Therefore, the slope-intercept form of a line that is represented by the table is
