[br][br]You will be given the equation of a straight line, in general form [math]y=mx+c[/math][br][br]* Drag the points A and B to the point where [color=#ff0000]y-intercept [/color]exist [math]\left(0,c\right)[/math][br]* Look at the value of [math]m[/math], where [math]m[/math] is [color=#0000ff]the gradient of the line[/color]. [br] [br] [math]m=\frac{rise}{run}[/math] [color=#ff7700] rise = vertical movement[/color][br] [color=#ff00ff]run = horizontal movement[/color][br][br]* Then drag one of the point (A or B) follow how many steps vertically and continued horizontally.[br][br][b][color=#ff0000]Example[/color][/b]: [br][br]The line [math]y=-3x+2[/math][br][br]* Drag both points to the y-intercept [math]\left(0,2\right)[/math] [br]* Value of [math]m[/math] is -3, it means rise = -3 and run = 1, or rise = 3 and run = -1[br]* So, drag on point A or B:[br] * 3 steps up (vertically) and 1 step to the left (horizontally) or[br] * 3 steps down (vertically) and 1 step to the right (horizontally)[br][br]* When the statement [b][color=#ff0000]"Great Job :)"[/color][/b] pops up, it means your answer is correct.[br][br]Please try 5 - 10 times, until you get the idea.[br][br]
