Question

The function f is defined by , where m and b are constants. If and , what is the value of m ?

Accepted Answer

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 . It&rsquo;s given that and ; therefore, the two ordered pairs for this line are and . Substituting these values for and gives , or 2.
