we have the equation
11x+6y=-33
Part A
Find the x-intercept (value of x when the value of y=0)
so
For y=0
substitute
11x+6(0)=-33
11x=-33
x=-3
therefore
the x-intercept is (-3,0)
Part B
Find the y-intercept (value of y when the value of x=0)
For x=0
11(0)+6y=-33
6y=-33
y=-5.5
therefore
the y-intercept is (0,-5.5)
Part C
Graph the given equation
Plot the intercepts, and join them to graph the line
