Assuming you want the equation is slope intercept form, this is the format for slope intercept: y=mx+b. Since you have the slope, this is your current equation: y=7/10x+b. Next, you want to find the y-intercept. So, plug in the coordinate to the equation. This is what it should look like: -1=7/10(0) +b/ Multiply 7/10 by 0 to get 0. So, here is what you're left with: -1=b. -1 is your y-intercept. Go back to your original equation and plug in the -1. This is your final answer: y= 7/10x-1. Hope this helped!
So there is 75 boxes of 12 right? You would figure out how much sticks you have by multiplying then you have to give them to 23 teachers. You take the total of sticks and divide among each teacher
