Please answer I need it asap you don’t have to show your work :)

= mx +b

m is slope, geometrically. It means that rate of change is fixed

i.e.

A plumber charges $30 for service and $20 for every hour of work.

then Cost of fixing depends on number of hours of work done:, and the relation is given by the following equation:

C = 20t + 30

$30 is service charge that is called start of the process

$20 is the rate(per unit) change, means that for every hour of work he charges $20 fix.

Linear relation is where Relation is represented by a binomial Expression( consist of 2 terms)

the coefficient of the variable( 20) is the fixed rate of change,

30 is the value of C at start of the point in the context of this problem will be service call.

In graph of the equation. $30 will be the C(vertical intercept), and $20 will be slope.

The feature of linear relation is that rate of change, rise/ run and slope is fixed.
