here is the question:
1.a)draw the graph of x^2 + y^2 = 25 and y = x + 1 on the same grid.
b) Use the graph to solve simultaneously the two equations.
is it allowed to plot the graph (after rearranging the formula) y = square root of 2 - x^2 (there isnt a square root key on the keyboard lol)
please help asap
thanx
xx

For more on marking an answer as the "Best Answer", please visit our FAQ.When you have a graph with axes x & y you cannot 'plot' y� as such so you need to rearrange it into the form y = ... so that for every value of x you put into the equation you get the corresponding value for y, with each pair x,y being a point on the graph.
You can also place as many equations as you find practical on one graph.
