Answer:
Slope is -3/7. Y intercept is 250/7.
Step-by-step explanation:
Since they asking for the slope and y intercept, let put it in slope intercept form.

where m is the slope and b is the y intercept.
The equation given is in standard form so we will convert it to slope intercept.




The slope is -3/7
The y intercept is 250/7
So if you're adding two negatives you move left, positive you move right, and when you have to determine a negative, and a positive you just have to see which one is the farthest from zero which the farthest one's sign is either positive, or negative. Positive to move right, and negative to move left.
