The rate of change of a linear equation (first degree) is equivalent to the slope of a line. Slope is described as the vertical movement (rise) of the line over its horizontal counterpart (run). In determining the rate of change or slope (m) given 1 data point (x',y'), point-slope form is applicable. Point-slope form is: (y-y') = m (x-x'). Substitute the given point (-5,-1) in the equation. By substitution, [y-(-1)] = m [x-(-5)]. Re-arranging the equation, the rate of change or slope is, m = (y+1)/(x+5).
2x+4y+0.50z=36 represents the situation.
Step-by-step explanation:
Let,
Drinks = x
Sandwich = y
And,
Chips = z
Total amount on these items = $36
According to the statement;
2x+4y+0.50z=36 represents the situation.

Answer:
a and c
Step-by-step explanation:
it would be a and c because the first expreesion in the sentace equals 54
<u><em>A and C are the only options that do not equal ( They both equal 24 not 54!) </em></u>
