As a previous comment suggested you can use Desmos calculator tool online for free to draw this line for you but it may be beneficial to also learn how the steps of graphing such lines by hand!
First, you are going to find the y-intercept of your graph. This is the place on the graph where it will cross the y-axis. To do so, you are going to set x equal to zero.
y = -4(0) + 5
y = 0 + 5
y = 5
The line will cross the y-axis at y = 5 so you will place a dot at coordinates (0,5) on your graph. From the origin (0,0) count 5 units vertically and place a dot.
Now, you will identify your slope, which is represented by the number in front of the variable x. In the slope-intercept form y = mx + b, this number is called m. In this equation, m = -4 or as a fraction m =
.
From your y-intercept (0,5) you will count down 4 units (because of the negative in front) and then count to the right 1 unit and place a point there. So that dot should be at coordinate (1, 1). For the next coordinates you are going to go back to your y-intercept at (0,5) and count up 4 units and then count to the left 1 unit (because of the negative in front) and place a point there. So that dot should be at coordinate (-1, 9).
If you want to plot more points to the left of the y-axis, you count up 4 units and left 1. If you want more points to the right of the y-axis, you count down 4 units and right 1.
Then you connect the dots and you are done! Desmos definitely helps to visualize these steps and to check your work but learning to do it is also essential in case you do not have a graphing calculator at-the-ready
