A:
Answer:C. Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.Step-by-step explanation:The two equations are in slope intercept form which is y = mx + b where m is the slope and b is the y-intercept. In the first equation (y = -2x + 3), -2 is the slope since it is the coefficient. "b" is 3 since it is the constant of the equation.In the second equation (y = -4x -1), -4 is the slope is the coefficient, and the y-intercept is -1 since it is the constant.To solve the equations graphically, graph them and find the point where they intersect.
