1) Put it in slope-intercept form:
y = mx + b
3x + 5y = -5
-3x. -3x
5y = -3x - 5
/5. /5
y = (-3/5)x - 1
2) Graph
Put a point on (0, -1) on y-axis
From that point move down 3 and
right 5. Put a point on (5, -4).
3) Draw a line through the 2 points and label it y = (-3/5)x - 1.

To graph the equation, solve to find the value of y. Use one of the arbitrary values of x. This will give you the equation in the form of y = mx + c. Plot a line on the graph using this solution. Solve for y using the other arbitrary values of x. Plot the point and then connect the two dots. The point they meet on the graph is the solution for x.

Well first you subtract 3x to the other side ... So it's 5y= -3x-5 then you divide by 5 : y= -3/5x-1 then you find -1 on the y axis (plot the point) and then go down 3 then over to the right 5 (plot the point) then down 3 over the right 5.
