Letter A is the answer to your equation problem
Answer:
9
Step-by-step explanation:
3/7 multiplied by 21 = 3/7 x 21 = 9 = 3/7 x 21/1 = 63/7 = 9
Or if you can't do the math - Think of a pizza with 21 slices . Now cut this pizza into 7 equal parts. You will find that each part contains exactly 3 slices. Now, eat 3 of these parts. With three slices in each part, you ate 9 slices - which is three sevenths of 21.

Answer:
By graphing the line, we have the equation y =
Step-by-step explanation:
What this question is asking us is to find the equation of the line with the value of the slope given in the question and also passing through the point in the question
For a straight line, the general equation can be represented as
y = mx + c
where m is the slope of the line and c is the y intercept. From the question, we have the value of the slope, what we have left to find is the value of the intercept. We find this by inserting the x, y and the slope value into the general equation of a straight line.
We have;
-3 = 3/4(2) + c
c = -3 - 6/4
c = -3-1.5 = -4.5
Thus, the equation of the line is;
y =
