I need help cuz im kinda stupid. A line that includes the points (10,–3) and (9,t) has a slope of –7. What is the value of t?
Pls, help me?

So subtract the Ys and subtract the Xs , then divide the answer you got for y over the answer you got for x. -3-t/10-9= -7, that simplifies to -3-t/1=-7 or -3-t=-7, from there you can add 3 to both sides to get -t=-4, which is the same as t=4. Plug it in to see if it’s makes sense . Hope this helps ; )

Add the cents that add the left overs to get the first number
