Answer: yes
hope it helped if it did don't forget to drop a heart
Step-by-step explanation:
The x-intercept of -2 gives us an idea that point (-2,0) if found along the line. The y-intercept of -1, tells us that point (0,-1), this also tells us that b = -1.
Now that we have two points, we can solve for slope m

Now that we have both m and b. Substitute these values to the slope intercept form
Answer:B
Step-by-step explanation:
B is has a proportional x and y value because they're increasing at the same rate which is 0
A) multiply equation A by -2 so you get -2x - 2z = -12 and then you can add both equations to eliminate z
