Answer:

1020 students

Step-by-step explanation:

Given the trend line equation :

y = 0.1x + 18,

where y is the total number of staff members and x is the total number of students.

Using the equation, the predicted number of students in a school with 120 staffs ;

y = 120

y = 0.1x + 18

120 = 0.1x + 18

120 - 18 = 0.1x

102 = 0.1x

x = 102 / 0.1

= 1020 students

What is the slope and Y intercept of the equation X=10

xenn [34]

Answer:

Slope is undefined and y int does not exist

Step-by-step explanation:

x=10 means it will be a vertical line where x= 10 so the slope is undefined and since it is perfectly vertical, it will never touch the y axis.
