The intersection of two planes is always a line
Answer:
y = -1/4x+2
Step-by-step explanation:
We can find the slope by finding two points on the line, and doing (y1-y2) ÷ (x1-x2). The two points I chose were (0,2), and (4,1). We can plug this into the equation to get (2-1) ÷ (0-4), to get -1/4, which is our slope. We can see on the graph, that the line intersects with the y axis when the y coordinate is 2, making the y-int 2.
The independent variable would be the fixed rate of $3 because the amount for each mile driven changes based on how far they drive
If you burned the same number of calories every minute while you kept biking for 45 minutes, and burned a total of 560 calories, then the number of calories burned per minute is 560/45=112/9
