A line that goes from (0, 12) to (3, 0) would have a slope of so
the slope of the line y = mx + 12 must be less than –4.4 . B
A line that’s perpendicular to y = –2x + 3 has a slope that’s the negative
reciprocal of –2, which is . That narrows the choices to (A) and (B). The
y-intercept of y = –2x – 3 is –3, and that’s the y-intercept in (B).
5 . A
Each of the answer choices is in the form of the product of two factors on
the left and a “≥ 0” or “≤ 0” on the right. The product will be negative
when the two factors have opposite signs, and it will be positive when
the factors have the same sign. Choice (A), for example, has a “≥ 0,” so
you’ll be looking for the factors to have the same sign.
Either:
