how do you solve and graph y=-2x+1

Question

Show me how to graph and solve this equation.

Answer 1

The equation is .

Use intercepts to graph the above equation.

The y - intercept is the value of y, when x = 0.

.

The y - intercept is 1, so the graph intersects the y - axis at.

The x - intercept is the value of x, when .

.

The x - intercept is , so the graph intersects the x - axis at .

Use these ordered pairs to graph the equation.

1.  Draw a coordinate plane.

2.  Plot the points.

3.  Draw a line through these points.

The solutions are x = 1/2 and y = 1.
