Using a scale of 2cm to 1unit on the x-axis and 2cm to 1unit on the y-axis.plot the graph of y-3x+4

Answer 1

To plot the graph of y - 3x + 4, we can start by creating a table of values for x and y. We will then plot these points on a coordinate grid.

Let's choose some values for x to start with:

When x = 0, y = 4 - 3(0) + 4 = 8
When x = 1, y = 4 - 3(1) + 4 = 5
When x = 2, y = 4 - 3(2) + 4 = 2

Now, we can plot these points on a coordinate grid using the given scale of 2cm to 1 unit on both the x-axis and y-axis.

Plot the point (0, 8) by moving 4 units up from the origin (0, 0) on the y-axis.

Plot the point (1, 5) by moving 2 units right and 2.5 units down from the point (0, 8).

Plot the point (2, 2) by moving 4 units right and 6 units down from the origin.

After plotting these points, you can draw a line connecting them to represent the graph of y - 3x + 4.

Note: Since the given equation is in the form y = mx + b, where m is the coefficient of x (-3 in this case) and b is the y-intercept (4 in this case), the graph is a straight line.
