Answer:

#x= -1 and y = -3#

Explanation:

The intercepts are the points on the axes.

All points on the x-axis have a y-value = 0.
All points on the y-axis have an x-value = 0.

To find the y-intercept, make x = 0 and solve for y.

#y=-3-3x# becomes #y = -3 -3(0)#

#y = -3#

To find the x-intercept, make y = 0 and solve for x.

#y=-3-3x# becomes # 0 = -3-3x#
#3x = -3#

# x = -1#
