Try this solution (based on 3 steps: equation of the line; points in this line; equation of the plane).
1. the equation is y=mx+b. m= slope and b= y-intercept so your answer should be y=2/3x+2
2. point-slope form is y-y1/x-x1=m answer is y+4=-1(x-1)
3. i give up im sorry my brain is fried ;-;
4.uhh i graphed it and attached an image lol
dang i- cant do no more math today lol sorry good luck
Answer:
Step-by-step explanation:

Answer:
multiplication, so d, 2 x 3
Step-by-step explanation:
remember... PEMDAS!!
x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
