Answer:
y = 65x + 250
Explanation:
Let the linear equation representing the relation between total pay and number of computers sold be,
y = mx + c
Here, m = commission on every computer sold = slope of the linear function
c = weekly salary
y = total pay
x = number of computer sold each week
Since, slope of the line passing through two points
and
is given by,
m =
![(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/kb22fsdtkimrfbfy51hnyncxhdjkkxel3s.png)
From the table attached,
Slope of the line passing through (4, 510) and (6, 640),
m =
![(640-510)/(6-4)](https://img.qammunity.org/2021/formulas/mathematics/high-school/o68tldaa1f9yvj5azofalgnrzwfwo0r5hl.png)
= 65
Equation of the line will be,
y = 65x + c
Since, this line passes through (4, 510),
510 = 65(4) + c
c = 510 - 260
c = 250
Therefore, equation of the line will be,
y = 65x + 250
