Question

I need the co-ordinates to answer this can anyone give them to me? If not it's fine! :)

Answer 1

Hi there!

Answer:

Find points for the equation y = 2x + 1 by plugging in x values:

For example, when x = 1, substitute in the value of 'x' into the equation:

y = 2(1) + 1

y = 2 + 1

Solve for the y-value:

y = 3

Repeat this process for multiple points:

X                               Y

-2                              -3

-1                                -1

0                                 1

1                                  3

2                                  5

To get the graph of y = 2x + 1, simply graph these points. :)
