Answer:
Option B)
Step-by-step explanation:
We are given the following in the question:
Priya uses cups of flour to make 3 loaves of banana bread.
Thus, we can write the ration of bread to amount of flour used as:
Now, b loaves of banana bread using f cups of flour.
This measurement will follow the same ratio.
Thus, we can write:
Thus, the correct answer is
Option B)
Answer:
<em>y = 3x - 17</em>
Step-by-step explanation:
Here is the point-slope form of the equation of a line.
If you are given a slope, m, and a point on the line, (x1, y1), you just plug in the values into the equation above, and you get the equation of the line.
In your problem, you are given a point on the line, (5, -2). Now you need the slope of the line. Your line is perpendicular to the given line. The slopes of perpendicular lines are negative reciprocals. If you know the slope of a line, the slope of its perpendicular is found by flipping the fraction and changing the sign.
The given line has slope -1/3.
Flip -1/3 to get -3.
Now change the sign to get 3.
The slope of the line you need is 3. The line passes through point (5, -2).
Now we use the point-slope equation and we plug in the values we have.
