Question 3 • Mathematics I

Line cap q cap r goes through points Q 0 comma 1 and R 2 comma 7 Which equation represents line cap q cap r ?

Answer
A
y minus 7 is equal to 2 x minus 6
B
y minus 7 is equal to x minus 2
C
y minus 1 is equal to 3 x
D
y minus 1 is equal to 6 x

Explanation

The slope through Q(0, 1) and R(2, 7) is (7 − 1)/(2 − 0) = 3. Using point-slope form with Q gives y − 1 = 3(x − 0), or y − 1 = 3x. This matches choice A.
