To graph y=-7x-3, you're going to make your first coordinate at (-3,0) b/c that is your y-intercept and you will continuously move down 7 and right one.
To graph y=4, you will simply make a horizontal line through the to coordinate (4,0).
Hope that helped.
Answer:
6/6
Step-by-step explanation:
6/6 not equal -1/1 so these lines intersect each other at only one point hence these have only one solution.
You add 9d+2d+3d which equals to 14d, then you would subtract 14d to each side. After you subtract 14d to each side, it should look like -4=-9d. So your answer should be 4/9=d
