The slope of this line is:
3-(-6)
m = ------------ = 1
3-(-3)
and so, using the point-slope formula for the equation of a str. line,
y-3 = 1(x-3), or y-3 = x - 3, or 1x - 3 - y + 3 = 0. Then 1x - 1y = 0 (in standard form). Alternatively, y = x (slope-intercept form).

More than means add
quotien t is divide
68+(x/54)=72
subtract 68
x/54=4
multiply both sides by 54
x=216
6 boxes of blueberry muffins and 8 boxes of corn muffins
Since we know that each box has 18 muffins, we can multiply both 6 and 8 to determine the amount of muffins present
6 • 18 = 108 blueberry muffins
8 • 18 = 144 corn muffins
To determine the price, you multiply each type of muffin by 0.50 as each muffin is worth $0.50
108 • 0.50 = 54
144 • 0.50 = 72
You add these two together to get the price
54 + 72 = $126
If you explain what the estimate is, if I didn’t answer that along the way, I can help answer it for you.
