About the exam
A straight line has equation y=mx + c, where m and c are constants
a) The point (2,7) lies on the line. Write down an equation in m and c to illustrate this information.
b) A second point (4, 17) also lies on this line. Write down another equation in m and c to illustrate this information.
c) Hence calculate the values of m and c.
d) Write down the gradient of this line.
c) By subtracting the equation obtained in a) from the equation obtained in b)
And by substituting m=5 into the equation in (a) or (b).
Note – Other methods are possible and acceptable.
a) Simplify √2 x √18
b) Simplify √2 + √18
c) Hence show that
