Answer: 180
Explanation: For the first number of the combination you have 60 possible options, because you need three numbers for the combo, times it by three.
We know that in order to solve a math problem, we need an equation. Luckily there's an equation to find the slope and intercept of a (straight) line!
Because of the equation:
Y = mx + b
You can use it to find the Y intercept, and then therefore slope (or the other way around)!
First, look at the point where the line meets with the y axis.
It's not clear, but it's 7.
That's your 'Y intercept'. Easy!
Then, to find the slope. There are a couple of ways to find it, but I'll show you the one using the y = mx + b equation.
In the equation, 'b' represents the Y intercept. Since we already know our Y intercept on the graph is 7, we can plug that into the equation.
Y = mx + 7
What's m? M is the slope of the line. In order to find this, we need more numbers to work with. Numbers from the line's coordinate points.
Since coordinates in a graph have x and y, we can plug in any coordinate from the graph's line into our equation (y = mx +7).
I choose...this point (points at random coordinate on line).
(3, 10) aka (x, y)
It's on the line, right? So it will be a reliable x and y.
Put the numbers in...
10 = 3m + 7
This looks a bit easier, right? Now we solve for m (the slope)!
Combine like terms.
10 - 7 = 3m
Divide the 3.
3/3 = m
m = 1.
That's your slope!
So, taking the solution, we can determine that the slope of the line is 1, and the intercept of the line is 7.
Y = x + 7
Hope it helps! This is the most I can do for you :)

Answer:
32.4kg
Step-by-step explanation:
if it loses one tenth of cement;
36kg×1/10
36kg/10
3.6kg was lost
to find the remaining ; 36kg - 3.6kg = 32.4kg is left in the bag
She paid $ 4 for renting a video game for 4 days...that means she paid $ 1 per day.
A horizontal axis is labeled days, a vertical axis is labeled cost of rental.
(x,y)...x is gonna be ur days and y is gonna be ur cost of rental
ur equation is gonna be y = x
points are plotted (1,1) , (2,2), (3,3)
