Hey there!
10(a - 2.5 + 0.56b)
= 10(a) + 10(-2.5) + 10(0.56b)
= 10a - 25 + 5.6b
= 10a + 5.6b - 25
Therefore, your answer is: 10a + 5.6b - 25
Good luck on your assignment and enjoy your day!

The chef can make 42 casseroles no remainder
Find the gradient:
m = y2-y1 / x2-x1
m = 6-(-4) / 0-1
m = 10 / -1
m = -10
Slope intercept form:
y = mx + c
Input the values from one of the points to find c (imputing (1,-4) to y=mx+c):
-4 = -10(1) + c
-4 = -10 + c
c = -4 + 10
c = 6
Therefore, the equation is:
y = -10x + 6
The first one 7/2 represents the change in y over change in x.
For those kinds of questions I would refer to the change in y over change in x method.
Bullet 3 would work because 7/2 doesn’t result to 1. So that’s not the answer.
I hope that helps
