Q. Which of the following equations represents a line that passes through the points (6,2) and (−6,−14) ?I. y−1=34(x−6)II. 4x−3y=21NeitherI onlyII onlyI and II
Calculate slope: Calculate the slope of the line passing through the points (6,2) and (−6,−14). The slope m is given by the formula m=x2−x1y2−y1. Here, (x1,y1)=(6,2) and (x2,y2)=(−6,−14). m=−6−6−14−2m=−12−16m=34
Check equation slope: Check if equation I, y−1=34(x−6), has the correct slope.The slope-intercept form of a line is y=mx+b.In equation I, the slope is 34, which matches the slope we calculated in Step 1.
Verify equation point: Verify if equation I passes through the point (6,2).Substitute x=6 and y=2 into the equation y−1=34(x−6).2−1=34(6−6)1=34(0)1=0This is incorrect; therefore, equation I does not pass through the point (6,2).
