Q. The equation 2y+3x=10 2 y+3 x=-10 is graphed in the xy x y -plane. Which of the following equations has a graph that is parallel to the graph of the given equation?\newlineChoose 11 answer:\newline(A) y=23x+52 y=-\frac{2}{3} x+\frac{5}{2} \newline(B) y=23x5 y=\frac{2}{3} x-5 \newline(C) y=32x5 y=\frac{3}{2} x-5 \newline(D) y=32x+52 y=-\frac{3}{2} x+\frac{5}{2}
  1. Parallel lines and slope: Two lines are parallel if they have the same slope. The given equation is 2y+3x=102y + 3x = -10. To find its slope, we need to write it in slope-intercept form, which is y=mx+by = mx + b, where mm is the slope.
  2. Converting the equation to slope-intercept form: First, we solve for yy in the given equation. Subtract 3x3x from both sides to get 2y=3x102y = -3x - 10.
  3. Finding the slope of the given line: Next, divide every term by 22 to solve for yy. This gives us y=32x5y = -\frac{3}{2}x - 5. Now we have the slope of the given line, which is 32-\frac{3}{2}.
  4. Checking the options for the same slope: We need to find the equation among the choices that has the same slope, 32-\frac{3}{2}. Let's check each option:\newline(A) y=(23)x+(52)y = -\left(\frac{2}{3}\right)x + \left(\frac{5}{2}\right) has a slope of 23-\frac{2}{3}.\newline(B) y=(23)x5y = \left(\frac{2}{3}\right)x - 5 has a slope of 23\frac{2}{3}.\newline(C) y=(32)x5y = \left(\frac{3}{2}\right)x - 5 has a slope of 32\frac{3}{2}.\newline(D) y=(32)x+(52)y = -\left(\frac{3}{2}\right)x + \left(\frac{5}{2}\right) has a slope of 32-\frac{3}{2}.
  5. Identifying the parallel equation: The only equation with a slope of 32-\frac{3}{2}, which is the same as the slope of the given equation, is option (D) y=(32)x+(52)y = -\left(\frac{3}{2}\right)x + \left(\frac{5}{2}\right). Therefore, the graph of this equation is parallel to the graph of the given equation.
