Step-by-step explanation
So we must give the slope, the y-intercept, the graph and the slope of a perpendicular line to the line given by the following equation:

The equation of a line in slope-intercept form is the following:

Where m is the slope and b is the y-value of the y-intercept. We can try to rewrite the equation given by the question so that it is written in slope-intercept form and we can use it to solve the first part. We can start by substracting 5x from both sides:

Then we can divide both sides by -3:

So we have m=5/3 and b=5.
In order to sketch the graph of a line we need at least two of its points. We can choose two random x-values and use them to find their corresponding y-values with the equation above. For example, we choose x=0 and x=-3 so we get:

So we must draw a line that passes through the points (-3,0) and (0,5).
Finally, the slope of a perpendicular line of a line given by y=mx+b is -1/m. In our case the slope is 5/3 so the slope of a perpendicular line is:

Answers
Slope = 5/3
y-intercept = (0,5)
The graph is:
Slope of a line perpendicular = -3/5
