Answer:
A) y - 2 = 3(x+4)
Step-by-step explanation:
Given that the equation is a line with slope =m=3 and
a point on it (x1,y1) = (-4,2)
Any line having slope m and passing through (x1,y1) has equation in point slope form as
y-y1 = m(x-x1)
We are given here x1 =-4, y1 =2 and m =3
y-y1 = y-2 and x-x1 = x-(-4) = x+4
So equation is y-2 = 3(x+4)
Verify:
The line is y = 3x+12+2 = 3x+14
Hence slope =3 is verified
Substitute the point x =-4 and y =2
2 =3(-4)+14 = 2 is true
Thus verified
Answer:
A is correct option. Equation of line: y-2=3(x+4)
Step-by-step explanation:
Slope of line is 3 and passing point (-4,2).
If slope and passing point given then we have an equation of line
[tex]y-y_1=m(x-x_1)[/tex]
where,
[tex](x_1,y_1)\rightarrow (-4,2)[/tex]
Slope (m)=3
Equation of line:
y-2=3(x+4)
This equation match with option A
Thus. option A is correct.
