Hello I have completed the questions, but not sure if I graphed my problems correctly. Thanks.
1.) Graph 3x + y = 5, showing the intercept coordinates.
My solution: y = -3x + 5
But you still need to find the x- and y-intercepts:
x-intercept: y = 0, -3x + 5 = 0, so
y-intercept: x = 0, y= 5, (0, 5).
To graph this line, we just need to connect the above ...
