Answer :
[tex]y=2x-1\\\\y-intercept\ (x=0)\\\\y=2\cdot0-1=-1\to(0;-1)\\\\x-intercept\ (y=0)\\\\2x-1=0\\2x=1\\x=0.5\to(0.5;\ 0)[/tex]
There are many ways to graph this equation.
Here's one that you should be able to manage:
-- Pick any number at all for 'x'.
[ y = 2x - 1 ], so double your number and subtract 1 to find 'y'.
Mark a point on your graph at (x, y) .
-- Pick any different number at all for 'x'.
[ y = 2x - 1 ], so double your number and subtract 1 to find 'y'.
Mark a point on your graph at (x, y) .
-- Using your pencil and ruler, connect the two points that you have marked
on your graph. Without moving the ruler, you may extend the line as far as you
want in each direction.
