Answer:
<h2>Graph b</h2>Step-by-step explanation:
The equation of a linear function in slope-intercept form:
m - slope
b - y-intercept
The graph of linear function is a straight line therefore we need only two points to the plotting the graph.
Now we have a negative exponent, which is the opposite of a positive exponent.
If a positive exponent means you're multiplying by 10s and it makes a number bigger by moving the decimal to the right, then
the opposite of this is that a negative exponent means you're dividing by 10s and making the number smaller by moving the decimal point to the left.
Examples:
The trick is to recognize that
is the same thing as
and
mean the same thing.
So,
For your exercise, means you'll move the decimal point 24 places to the left, to make the number smaller.
