The equation for the straight line that passes through (x1,y1) & (x2,y2) can be found here
Now, the equation for the straight line that passes through (-4, 20,) and (–2.5, 15.5), is:
Take the first point.
Now, let’s take the first point, i.e. x=-2 and then y=14.
Take x=-1.25 and y=12.5, and you get.
Take x=-1 and then y=11 to get.
As such, the points (-2.14, (-18.104.22.168), and -1.11 are collinear.
L’ = 3x+y-8=0.
For the intersection:
These two intersect at (104/17,11/17)
Plotting of 4*x+ = 5
Plotting of 14x+11y=25
Plotting of 2*x+3*y=5
Let’s solve the 4x+y=5 problem and the 2x+3y=5 problem
You can put x=1 as well as y=1 at 14x+11y-25=0
The system has a unique solution because the three straightlines intersect at a singular point.
The minimum fare for a trip is $6.20. This is also the yintercept in the graph. Here, the y-axes represent total fare and the x-intercept distance (in kilometers).
So $6.20 is the cost of sitting in the vehicle.
The straight line intersects the zero-point y-axis, so we can conclude that (0.6.20) is the intersection.
You pay $5.25 per mile.
Accordingly, the equation for the straight line is
where y represents the fare and the distance
This makes the distance 32.0km.
So the total fare for this trip is y=5.25*32 – 6.2 = 174.20 $
We have f (x)=x3 – 3*x+ 1
Because the price per kilogram of banana is quadratic we have a function like this.
Now, we have, -eqn1
The following is the list:
Here we are,

Below is the program.
