Your answer is y = -3x + 1
To find the equation of the line we need both the slope and where it intercepts the y-axis. We are given where it intercepts the y-axis because they tell us it goes through the point (0, 1) and this is a point where x = 0, so it must be on the y-axis.
The equation for finding the slope of a line given two points is where and are points on the line. Using this, we can substitute in the points we're given and get:
(-5 - 1)/(2 - 0) = -6/2 = -3
Therefore our slope is -3 and our intercept is 1, so the final answer is y = -3x + 1
I hope this helps!
Answer:
Jordan's line would go up and Trevor's line would go down. This is because Jordan's like has a positive slope and Trevor's has a negative slope

Step-by-step explanation:
Let x be the number of buses for the trip.
Then (32 - x) is the number of cars for the trip.
We have 27x + 3(32 - x) = 408.
=> 27x + 96 - 3x = 408
=> 24x = 312
=> x = 13
Hence there are 13 buses and (32 - 13) = 19 cars.

One way is just to recognize that
2.88=12 cookies
konw that
12/6=2
so divide both sides by 6
0.48=2 cookies
2 cookies is 48 cents
ratio and proportaion way
cost:cookies=2.88:12
cost of 2 cookies is x
2.88/12=x/2
times both sides by 12
2.88=6x
divide both sides by 6
0.48=x
the cost is 2 cookies is $0.48 or 48 cents
