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) and (−3,3) ?
Calculate Slope: We need to find a linear equation that passes through the points (2,−2) and (−3,3). To do this, we will use the point-slope form of a linear equation, which is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line.
Use Point-Slope Form: First, we calculate the slope m using the two given points (2,−2) and (−3,3). The slope formula is m=x2−x1y2−y1. So, m=−3−23−(−2)=−55=−1.
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). Using the point-slope form, we get y−(−2)=−1(x−2).
Convert to Slope-Intercept Form: Simplify the equation to get it into slope-intercept formy=mx+b.y+2=−1(x−2)y+2=−x+2y=−x+2−2y=−x
Final Linear Equation: We have found the linear equation y=−x that passes through the points (2,−2) and (−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) and (−3,3).
