How do you graph #y = 4x - 3# by plotting points?

Start at (0,-3) and then go up 4 right 1

To graph #y=4x-3# you would first graph the y-intercept, -3, and then using the slope, 4, to complete the rest of the graph. Start at point (0,-3) then go up 4 right one which would leave you at point (1,1), the second point and you would continue going up 4 right one to plot each point. TO build the graph backwards, you could go down 4, left one which would leave you at point (-1,-7)

undefined To graph the equation y = 4x - 3 by plotting points, you can choose a few values for x, calculate the corresponding values of y using the equation, and then plot these points on a coordinate plane. Here's a simple approach:

Choose three values for x. For example, let's choose x = -2, 0, and 2.

Substitute each value of x into the equation y = 4x - 3 to find the corresponding values of y.
For x = -2: y = 4(-2) - 3 = -8 - 3 = -11
For x = 0: y = 4(0) - 3 = 0 - 3 = -3
For x = 2: y = 4(2) - 3 = 8 - 3 = 5

Plot the points (-2, -11), (0, -3), and (2, 5) on the coordinate plane.

Draw a straight line passing through these points. This line represents the graph of the equation y = 4x - 3.
