Answer:
a, b, d
Explanation:
Sara's equation is in slope-intercept form:
y = mx + b . . . . . . . m is the slope, b is the y-intercept
Two lines with the same y-intercept will intersect at that y-intercept, the point where each crosses the y-axis.
Two lines with the same slope will be parallel.
Two lines with slopes whose product is -1 will be perpendicular.
__
(a) TRUE -- y = 3x+5 intersects at the y-intercept
(b) TRUE -- y = -2/3x -5 is parallel
(c) False -- y = 2/3x -5 has a different slope, so is not parallel
(d) TRUE -- y = 3/2x -5 is perpendicular: (-2/3)(3/2) = -1
(e) False -- y = 2/3x +3 has a different slope from a perpendicular line
