Answer: y=3x+1
Step-by-step explanation:
First find slope using formula
m= y2–y1/x2–x1
m= 4– (—2)/ 1— (—1)
m= 3
So,
y= mx+b
y=3x+b. Using (1,4) plug into equation of a line
4= 3(1)+b
4 – 3= b
1= b. So,
y=3x+1
Answer:
y= 3x+1.
Step-by-step explanation:
(-1,-2) and (1,4)
x1 = -1
x2= 1
y1= -2
y2=4
y - y1= (y2 - y1)
______ ( x - x1)
(x2 - x1)
y- (-2)=(4-(-2))
_____ (x- (-1))
(1-(-1))
y+2= 4+2
___ (x+1)
1+1
y+2= 6
_ (x + 1)
2
y+2=3(x+1)
y+2=3x+3
y=3x+1.
