Answer:
(10,0), -(10,0) (0,10) and (0.-10)
Step-by-step explanation:
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)
Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)
Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.
Answer: There is difference of $660 in their paychecks.
Step-by-step explanation:
Since we have given that
Number of hours in one week they worked = 40
Amount of sales = $78000
Kent makes $10 per hour plus 3% on the amount of sales .
So, the equation for Kent becomes,
![10\times 40+\frac{3}{100}\times 78000\\\\=400+3\times 780\\\\=400+2340\\\\=\$2740](https://tex.z-dn.net/?f=10%5Ctimes%2040%2B%5Cfrac%7B3%7D%7B100%7D%5Ctimes%2078000%5C%5C%5C%5C%3D400%2B3%5Ctimes%20780%5C%5C%5C%5C%3D400%2B2340%5C%5C%5C%5C%3D%5C%242740)
Similarly, Bradley only makes $7 per hour but he makes 4% on the amount of his sales .
So, the equation for Bradley becomes,
![7\times 40+\frac{4}{100}\times 78000\\\\=280+4\times 780\\\\=280+3120\\\\=\$3400](https://tex.z-dn.net/?f=7%5Ctimes%2040%2B%5Cfrac%7B4%7D%7B100%7D%5Ctimes%2078000%5C%5C%5C%5C%3D280%2B4%5Ctimes%20780%5C%5C%5C%5C%3D280%2B3120%5C%5C%5C%5C%3D%5C%243400)
hence, the difference between of their paychecks is given by
![\$3400-\$2740\\\\=\$660](https://tex.z-dn.net/?f=%5C%243400-%5C%242740%5C%5C%5C%5C%3D%5C%24660)
Therefore, there is difference of $660 in their paychecks.
