A line contains the points (4,2) and (0,-1). what is the equation of the line. a) y=2x -6 b)y= 3/4x -1

c) y= 1/4x + 1

d) y= 4/3x - 10/3

To do this, we should calculate the gradient first

m=y2-y1 overx2-x1

m=-1-2 over 0-4

m=-3 over -4

m=3 over 4

formula of a straight is y-y1=m(x-x1)

y-2=3/4x-3

y=3/4x-1

so the answer is b)

m=y2-y1 overx2-x1

m=-1-2 over 0-4

m=-3 over -4

m=3 over 4

formula of a straight is y-y1=m(x-x1)

y-2=3/4x-3

y=3/4x-1

so the answer is b)

A software company startes with 2 employees. in 6 months, the company has u employees. the number of employees increased at a steady rate. which equation models the relationship between the number of employees n and the number of months m since the company started?

The company started with 2 employees. With the information that the amount of employees grew at a steady rate per month, we could simply solve this equation by multiplying 2 by 6 to get the number of employees the company now has. The company now has 12 employees.

If x<5 and y<6, then x+y__ 11

is it <,>,=?

To solve for this, let's try the highest number x and y can be.

X < 5, so it can be 4.

Y < 6, so it can be 5.

4 + 5 = 9.

9 < 11, so x + y < 11.

Your missing inequality symbol is:

X < 5, so it can be 4.

Y < 6, so it can be 5.

4 + 5 = 9.

9 < 11, so x + y < 11.

Your missing inequality symbol is:
