Answer:
-3x+y = 25
Step-by-step explanation:
Step 1 ) You can use the formula for each 2 set coordinates called points y2-y1 /x2-x1 =37-25/4-0 = 12/4 =3/1 then 49-37/8-4 = 12/4 = 3/1 then 49- 25/ 8-0 =24/8= 3/1 therefore 3/1 = 3 is the y/x relationship for y determining x and is also the gradient m = 3 Step 2) We can now answer the equation slope +y intersect form y = mx+c to show y=3x+c c= 25 therefore y = 3x+24 Step 3) Now you have got the formula and placement you can now rearrange until any fit true to what we have found = y-3x=25 is the same as -3x+y = 25 is the only correct answer unless moving 25
