У=3х-4,5

The equation given is y = 3x - 4.5. Let's break it down:

The equation is in the form y = mx + b, where m is the slope and b is the y-intercept.

The slope (m) is the coefficient of x, which is 3 in this case. It tells us how much y changes for every 1 unit increase in x.

The y-intercept (b) is the constant term, which is -4.5. It tells us the value of y when x is 0.

So, in this equation, the slope is 3 and the y-intercept is -4.5.

To draw the graph of this equation, you can start by plotting the y-intercept, which is -4.5 on the y-axis. Then, you can use the slope to find other points and connect them to form a straight line.

Alternatively, you can use the values of x to calculate the corresponding values of y and plot the points. For example, when x = 0, y = -4.5, when x = 1, y = -1.5, when x = 2, y = 1.5, and so on.

Once you have plotted enough points, you can connect them to form a straight line that represents the equation y = 3x - 4.5.
