Question

Find the slope of a line that contains (0, 3) and (3,9)

A. m = 2
B. m = - 2
C. m = 1/2
D. m = - 1/2

Answer 1

answer is 2. The formula for gradient of a line or slope is y square- y-one divided by X- square minus X-one. according to the question, 0 is X-one and 3 is Y-one then 3 in the second bracket represents X square and 9 represents Y square. Now if you follow the formula I gave you would get your answer.
