Solve the problem. Write all linear equations in slope-intercept form.
-In a lab experiment 6 grams of acid were produced in 21 minutes and 18 grams in 31 minutes. Find a linear equation that models the number of grams produced in $x$ minutes.
A) $y = \frac { 6 } { 5 } x + \frac { 96 } { 5 }$
B) $y = \frac { 6 } { 5 } x - \frac { 96 } { 5 }$
C) $y = x + 15$
D) $y = \frac { 5 } { 6 } x - \frac { 5 } { 96 }$

Question

Quizplus · Accepted Answer

The slope of the line is calculated using the points (21, 6) and (31, 18), which gives a slope of $\frac{6}{5}$. Using the point-slope form and converting to slope-intercept form, the equation is $y = \frac{6}{5}x - \frac{96}{5}$.
