Question 21 • Mathematics I

To graph the equation 2 x plus 5 y is equal to 10 , Zeplyn draws a line through the points 5 comma 0 and 0 comma 2 What is the slope of the line represented by 2 x plus 5 y is equal to 10 ?

Answer
A
negative 2 fifths
B
5 halves
C
2 fifths
D
negative 5 halves

Explanation

The line passes through (5, 0) and (0, 2). Its slope is the change in y divided by the change in x: (2 − 0) / (0 − 5) = 2 / (−5) = −2/5. Therefore, the slope is negative 2 fifths, choice A.
