a straight line in the xy - plane has y - intercept of 12 and a slope of 4 / 7 . given the x - coordinate of the point is 49 , find it ' s y - coordinate .
"eq of line = y = mx + c m = 4 / 7 c = 12 x = 49 substitute the givens : y = ( 4 / 7 * 49 ) + 12 , y = 16 + 12 = 28 correct option is d"
divide(subtract(7, 12), 4)
