Q. Which of the following equations represents a line that passes through the points (0,3) and (−10,−17) ?I. y−11=2(x−6)II. y=2x+5NeitherI onlyII onlyI and II
Calculate Slope: First, let's find the slope of the line that passes through the points (0,3) and (−10,−17). The slope m is calculated using the formula m=x2−x1y2−y1, where (x1,y1) and (x2,y2) are the coordinates of the two points.m=−10−0−17−3m=−10−20m=2
Find Equation: Now that we have the slope, we can use the point-slope form of the equation of a line, which is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line. We can use the point (0,3) to find the equation of the line.y−3=2(x−0)y−3=2xy=2x+3This is the equation of the line that passes through the points (0,3) and (−10,−17).
Check Equation I: Let's check if equation I, y−11=2(x−6), represents the line that passes through the points (0,3) and (−10,−17). We can simplify this equation to see if it matches the equation we found.y−11=2(x−6)y=2x−12+11y=2x−1This equation does not match the equation y=2x+3 that we found, so equation I does not represent the line that passes through the given points.
Check Equation II: Next, let's check if equation II, y=2x+5, represents the line that passes through the points (0,3) and (−10,−17). We compare this equation to the equation we found, y=2x+3. Since the equation y=2x+5 has a different y-intercept than the equation y=2x+3, equation II also does not represent the line that passes through the given points.
Final Answer: Since neither equation I nor equation II matches the equation y=2x+3, which is the correct equation of the line that passes through the points (0,3) and (−10,−17), the correct answer is "Neither."
