mark is a new plumber. for a repair job, mark charges his customers for the parts required to make repairs and a certain amount per hour
spent making repairs. the time he spent making repairs and the total amount he charged a customer are given in the table for four repair jobs
number of hours, x 1 3 4 6
total charge, y($) 100.00 188.80 195.00 365.10
a line of best fit for the data is given by the equation below.
y = 51.25 + 32.96
choose the correct meaning of the rate of change and yuintercept of the line of best fit from each column of the table
rate of change
the increase in number of hours
worked per dollar charged
the amount the charges increase for
each additional hour of work
intercept
the increase in number of hours
worked per dollar charged

rate of change: the amount the charges increase for  each additional hour of work

y-intercept: the average cost of parts for each visit

Step-by-step explanation:

In the context of the problem, x-variable represents Number of Hours and y-variable represents Total Charge. The rate of change represents how much y varies for an unit variation in x. For this problem, that means how much the cost increase when 1 more hour of work is done. The y-intercept is the value of y when x = 0. For this problem, that means how much cost is charged when zero hours are worked. Given that Mark charges his customers for the parts required to make repairs and a certain amount per hour, the y-intercept represents the average cost of the parts required.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
