a line passes through the point (-3,-4) and its y-intercept is (0,9). what is the equation of the line that is parallel to the first line and passes through the point (3,-7)?
You have a mistake in your question... y-intercept must be ( 0, -9 ), because with coordinates ( 0, 9 ) there is no answer. The line equation of the 1st line: -4 = -3m - 9 3 m = - 9 + 4 3 m = -5 m = - 5/3 If the 2nd line is parallel to this one m-value is also -5/3. -7 = - 5/3 · 3 + b - 7 = - 5 + b b = - 2 Answer: C ) y = - 5/3 x - 2
