Q. A quadratic equation is graphed. Which of the following equations could be paired with the graphed equation to create a system of equations whose solution set is comprised of the points (2,2) (2,-2) and (3,3) (-3,3) ?
  1. Calculate Slope: We need to find a linear equation that passes through the points (2,2)(2,-2) and (3,3)(-3,3). To do this, we will use the point-slope form of a linear equation, which is yy1=m(xx1)y - y_1 = m(x - x_1), where mm is the slope and (x1,y1)(x_1, y_1) is a point on the line.
  2. Use Point-Slope Form: First, we calculate the slope mm using the two given points (2,2)(2,-2) and (3,3)(-3,3). The slope formula is m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}. So, m=3(2)32=55=1m = \frac{3 - (-2)}{-3 - 2} = \frac{5}{-5} = -1.
  3. Simplify Equation: Now that we have the slope, we can use either of the two points to write the equation. Let's use the point (2,2)(2,-2). Using the point-slope form, we get y(2)=1(x2)y - (-2) = -1(x - 2).
  4. Convert to Slope-Intercept Form: Simplify the equation to get it into slope-intercept form y=mx+by = mx + b.\newliney+2=1(x2)y + 2 = -1(x - 2)\newliney+2=x+2y + 2 = -x + 2\newliney=x+22y = -x + 2 - 2\newliney=xy = -x
  5. Final Linear Equation: We have found the linear equation y=xy = -x that passes through the points (2,2)(2,-2) and (3,3)(-3,3). This linear equation, when paired with the graphed quadratic equation, will create a system of equations whose solution set is comprised of the points (2,2)(2,-2) and (3,3)(-3,3).
