Research question: Does the distance a person kicks a soccer ball affect how well they will do on their math test? What is the dependent variable?
A. Who the person is
B. How well they do on the math test
C. Type of soccer ball
D. How far they kick the soccer ball
Answer (2)
for the first table consider A(x1,y1)=A(0;3) and B(x2;y2)=B(1;5)
the slope m= (y2-y1)/(x2-x1) = (5-3)/(1-0) = 2/1=2
for the second table consider again A(x1;y1)=A( 0;9) and B(x2;y2)=B(2;4)
the slope m= (y2-y1)/(x2-x1)= (4-9)/(2-0)= -5/2= -2.5
To find the slope of a line given two points, you can use the formula m = x 2 − x 1 y 2 − y 1 . For points A(0, 3) and B(1, 5), the slope is 2, while for points C(0, 9) and D(2, 4), it is -2.5. The sign of the slope indicates whether the line rises or falls from left to right.
