Answer:
(0, -2)
Step-by-step explanation:
The y-int is where the graph crosses the y-axis when x = 0. The easiest and fastest way to do this problem is to graph the equation using a graphing calc and tracing the graph to find your value.
Answer: 480
Step-by-step explanation:
First, find how much he go per hour by dividing 144 by 3. Which is 48. Then multiply that by 10 which gives us 480.
The gradient of the original line is 4. For a perpendicular gradient, you use the negative reciprocal, which is -1/4. Using y - y1 = m(x - x1), you can solve that y - 5 = -(1/4)(x - 2).
Multiply through by -4, you get -4y + 20 = x - 2, which can be rearranged as x + 4y = 22
