1.Find the coordinates of the point where the line 2y=x-4 cuts the x axis.
Find the equation of the straight line through this point and (-1,10)
Are the coordinates and the equation of this question connected? I have done this exercise few months ago but I have forgotten everything. Some explaining would be nice.. :)
2.Find the coordinates of the point where the line 2y=-x+6 cuts the x axis.
Find the equation of the straight line through this point and the point (8,8)
3.If f(x)=2x+10 and g(x)=x^2-3x-4
Find
a.f(2)+g(2)
b.f(x)+g(x)
c.f(2x)+g(2x)
d. the values of p for which g(p)=0
e.The values of q for which f(q)=g(q)
Thx in advance :)
