Answer:
y + 1 = 3(x - 4)
Step-by-step explanation:
slope formula is (y - y1) = m (x - x1)
so plug in the information and you get
(y - (-1)) = 3 (x - (4))
Answer:
Y = 3x-13
Step-by-step explanation:
y= mx+b
4 = x and -1 =y
(4,-1)= (x,y)
m=3= slope
y=mx+b
-1=3(4)+b
-1=12+b
you subtract 12 on both sides
b = -13
Y = 3x-13
