Directions: Using the integers -9 to 9, at most one time each, place a digit in each box to make a linear equation which goes through (5, 4) and has a slope that’s as close to 0 as possible without being horizontal.
Hint
How can you determine whether your line intersects the point (5, 4) algebraically? How can you determine whether your line intersects the point (5, 4) graphically? Here’s a link to an already set up Desmos version. How can you determine if your linear equation’s slope is closer to 0 than another student’s slope?
Answer
The equations of the lines that goes through (5, 4) and has a slope that is as close to 0 as possible without being horizontal are y = (1/-5)x + 5 and y = (1/5)x + 3.

The answer is not the above answer. It is y = (1/5)x + 3
This is what I got too and the slope is closer to 0.
Yep, you’re both right. Not sure how I messed that up but I was just coming to check the answer when I just did it and I was like, “That answer can’t be right.”
