The function f is defined by , where m and b are constants. If
and
, what is the value of m ?
Explanation
The correct answer is 2. The slope-intercept form of an equation for a line is , where m is the slope and b is the y-coordinate of the y-intercept. Two ordered pairs,
and
, can be used to compute the slope using the formula
. Itβs given that
and
; therefore, the two ordered pairs for this line are
and
. Substituting these values for
and
gives
, or 2.
