Astraight line joins the points (-1, -4) and (3, 8)
i) find the midpoint of this line
ii) find the equation of this line. give your answer in the form y=mx+c

i)(2,4)

ii)y=3x+c

Step-by-step explanation:

I. minus them from each other

ii. draw out the graph to find the gradient, which is rise over run, this is your m and c can be any number since it is a never ending straight line.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
