The answer is 3. If you set it up in a T table and label x as the number of hours and y as the number of rows. Then use rise over run (y over x) the fractions simplify to 3 over 1.
Answer:
The gradient of lines A is 8 and B is -4
Step-by-step explanation:
As we know, the gradient of a line is its slope.
The formula to find the slope of a linear line is:
m =
As we can see the line A goes through points:
C (x1, y1) = (0, -6)
D (x2, y2)= (2.5, 14)
<=> the slope of line A is:
=
=
=
As we can see the line A goes through points:
E (x1, y1) = (2, 0)
F (x2, y2)= (0, 8)
<=> the slope of line B is:
=
= -4
Hence, the gradient of lines A is 8 and B is -4
C + D go together
B + F go together
A + F go together
Hope this helps c:
T=0 is also a solution. Other than 0 here is a solution.
