Find an equation of the line that goes through the points (8,-45) and (2,-9). Write your answer in the form y = mx + b.

Linear equations are commonly organized in slope-intercept form:

To find the equation of a line given two points:

We're given:

First, determine the slope using the following formula:

where the given points are and

⇒ Plug in the given points (8,-45) and (2,-9):

Therefore, the slope of the line is -6. Plug this into as m:

Now, determine the y-intercept:

⇒ Plug in one of the given points as (x,y) and solve for b:

Therefore the y-intercept of the line is 3. Plug this back into :

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The total nom of  code that can be used is equal to 5+3 = 8

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The answer is in the image 

The solution is given in the image below

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76
