Q. The equation 2y+3x=−10 is graphed in the xy-plane. Which of the following equations has a graph that is parallel to the graph of the given equation?Choose 1 answer:(A) y=−32x+25(B) y=32x−5(C) y=23x−5(D) y=−23x+25
Parallel lines and slope: Two lines are parallel if they have the same slope. The given equation is 2y+3x=−10. To find its slope, we need to write it in slope-intercept form, which is y=mx+b, where m is the slope.
Converting the equation to slope-intercept form: First, we solve for y in the given equation. Subtract 3x from both sides to get 2y=−3x−10.
Finding the slope of the given line: Next, divide every term by 2 to solve for y. This gives us y=−23x−5. Now we have the slope of the given line, which is −23.
Checking the options for the same slope: We need to find the equation among the choices that has the same slope, −23. Let's check each option:(A) y=−(32)x+(25) has a slope of −32.(B) y=(32)x−5 has a slope of 32.(C) y=(23)x−5 has a slope of 23.(D) y=−(23)x+(25) has a slope of −23.
Identifying the parallel equation: The only equation with a slope of −23, which is the same as the slope of the given equation, is option (D) y=−(23)x+(25). Therefore, the graph of this equation is parallel to the graph of the given equation.
