Write an equation that is parallel to 3x â 2y = 14 and passes through the point (-6, -11) in slope-intercept form.
Parallel lines have the same slope. Get the given equation in slope-intercept form to find the slope.
Slope-intercept form is y = mx + b m is the slope b is the y-intercept 3x - 2y = 14 {given equation} -2y = -3x + 14 {subtracted 3x from each side} y = (2/3)x - 7 {divided each side by -2} slope = 2/3 Use slope-intercept form, with the point and the slope, to get the equation of the line. Substitute (-6,-11) in for x and y, and 2/3 in for the slope. Find the y-intercept, then substitute it back in, with the slope, into slope-intercept form. (-6,-11), m = 2/3 {point and slope} y = mx + b {slope-intercept form} -11 = (2/3)(-6) + b {substituted point and slope into slope-intercept form} -11 = -4 + b {multiplied 2/3 by -6} b = -7 {added 4 to each side} y-intercept is -7 y = mx + b {slope-intercept form} y = (2/3)x - 7 {substituted point and slope into slope-intercept form} Use the graphing calculator to check if the point does lie on the new line.
