Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total cost. the total cost for 35 brochures is $41.45. the total cost for 65 brochures is $55.55. step 1: write the ordered pairs mc017-1.jpg and mc017-2.jpg. step 2: find the slope. mc017-3.jpg step 3: find the y-intercept to write the equation in slope intercept form. mc017-4.jpg which explains the error that lila made? lila made in error in step 1 by reversing the ordered pairs. lila made an error in step 2 by not using the slope formula. lila made an error in step 3 when she did not use the x- and y-coordinates from the same ordered pair.
