Question

Draw the straight line graph of the given function y = -2x+1 ; -2

Answer 1

Answer:

y = 2 (0) - 1

y = -1

To find the x-intercept, put y = 0

2x - 1 = 0

2x = 1

x = 1/2

Draw your system of axis. Mark -1 on the y-axis, and 1/2 on the x-axis.

Now draw a line through these two ponts. Add arrows.

==============================================

To draw the graph by using points,

let x = -1, then y = 2 (-1) - 1 = -2 - 1 = -3

first point is (-1; -3)

Let x = 0, y = 2 (0) - 1 = -1

Second point is (0; -1)

Let x = 1, y = 2(1) - 1 = 1

Third point is (1; 1)

Plot the three points and draw a line through them. Add arrows to your line.
