Discrete Quantitative Questions

1. −^25 Isolate y to put the equation into slope-intercept form:
   2 x + 5y − 3= 12
   2 x + 5y = 15
   5 y = −2x + 15
   y = −2x + 15 5
   y = −^25 x + 3
   The slope is −^25.


2. C Substitute the coordinates into the equation for the line. The coordinates
   that satisfy the equation will be the answer. Of the choices, only (12, 24)
   satisfies the equation. For illustration: 3(12) – 2(24) = 36 – 48 = −12.
