U have a solid line...meaning there is an equal sign in the problem u have a y int of -1 (the y int is where ur line crosses the y axis) u have a slope of : 1 it is shaded below the line...so it is less then
First, let's work out the equation of the graph. We can see that for every 1 in x, the y coordinate increases by 1, which means the gradient is 1. The line intercepts the y axis at -1, meaning the equation of our line is y = x - 1 An inequality in this case basically represents which side of the line we want to be on - do we want the numbers to be greater than the line (i.e. above the y value) or less (i.e. below the y value)? The shading here shows us they want the value set below the line, i.e. less than it.
you multiply 20 times 45. 20 for the cost of adults and 45 for how many adults. and then you mulitpy 600 times 15 because children cost 15 dollars and their was 600 children. and then you add both up to get 9,900
