To find the slope you use the slope formula y2-y1 / x2-x1. So use two point on the line we will make ours (1,2) and (3,4). Substitute to make 4-2 / 3-1 = 1/1 so using the rise over run method. The line rises up one and runs by one. The slash mark means divide, it's easiest in a fraction.
Also if you come across the equation y=mx+b, m is the slope and b is the y-intercept, this is called slope intercept formula.
Answer:
40
Step-by-step explanation: If 10 : 15, then 4 times both of those should be an hour. This would be 40 : 60. That is why 40 is the correct answer.
Answer:
9
Step-by-step explanation:
Assuming x is the multiplication symbol, you would multiply 3 and the other 3 together. This leaves you with 9+7-7. Since 7-7=0 you can just get rid of both sevens completely. Now you are only left with 9.
Answer:
7
Step-by-step explanation:
Answer:
30.67 feet
Step-by-step explanation:
A proportion is often useful for solving scale drawing problems.
actual size : drawing size = (room length) : (23 in) = (2 ft) : (1.5 in)
Multiplying by 23 in gives ...
room length = (2 ft)(23 in)/(1.5 in) = 46/1.5 ft = 30 2/3 ft
room length ≈ 30.67 ft.
