The strategy for these is to look at what these problems are telling you.
It says the y-value, so you know that this is a y = equation.
y = what?
y = 2 more than. 4 is two more than 2, right? So saying it's more than is another way of saying "y is 2 + blah blah."
So y = 2 + what? Three times the x-value. What does that mean? 3*X = 3X.
Thus we arrive at the final answer, y = 3x + 2
Answer:
The slope is 0
The line is a horizontal line
The line has no y-intercept
Answer:
<em>B) Kara's highest speed was between 30 and 35 minutes.</em>
Step-by-step explanation:
A zero slope (horizontal line) means a stopped car with zero speed.
The higher the slope, the steeper the line, the higher the speed.
Let's look at the options.
a) The car was stopped between 10 and 15 minutes, not 20. False.
b) Between 30 and 35 min, the graph shows the steepest slope, so this statement is True.
c) False, since here slope is not steepest.
d) Between 5 and 10 minutes, the graph is a straight line, so speed was constant. False.
