A function that fits the following points (0,5), (2,-13) is y = 9x + 5
<h3>Equation of a line</h3>
The equation of a line in slope-intercept form is expressed as;
y =mx +b
where;
m is the slope
b is the intercept
Given the following coordinates (0,5), (2,-13)
Slope = -13-5/2-0
Slope = -18/-2
Slope = 9
Since the y-intercept is b = 5, hence the equation of the line will be y = 9x + 5

<span>Jack Watkins earns a base salary of $1500 a month, plus a 4% commission on the sales he makes. What is his gross pay of his sales for the month are $8000.
solution:
Gross pay=(salary)+(commissions)
base salary=$1500
commission=4%
monthly sales=$8000
commissions earned in cash
=4/100</span>×8000
=$320
thus
Gross salary=320+1500=$1820
Answer:
17.67 mpg
Step-by-step explanation:
The fuel efficiency is given by :
We need to find the fuel efficiency for a speed of 30 mph
Put the value of s equals 30 mph in the above equation.
So, the required fuel efficiency is equal to 17.67 mpg.
G(f(4)) = g(4-7) = g(-3) = (-3)² = 9
g(f(4)) = 9
