Answer:
Step-by-step explanation:
Gradient of a line =( y2 - y1)/x2 - x1
From the question, x1=4,y1=-1,x2=1,y2=0.
Therefore, substitute for these values in the above formula
m = 0-(-1)/1-4
= 0+1/-3
= -1/3.
Therefore, y-y1/x-x1 = -1/3
y - y1 = -1/3(x - x1)
y - (-1) = -(x-x1)/3
y+1 = - (x - 4)/3
Multiply through by 3
3y+3= -x+4
3y +x=4-3
x+3y= 1
Therefore the answer is A.
The required equation of the line passing through the points (4, -1) and (1, 0) is x + 3y = 1
The correct option is (A).
Equation of a Line:
If any line passing through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] then the equation of the line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
How to calculate equation of the line?
Here we have given that the points [tex](x_1,y_1)=(4, -1)[/tex] and [tex](x_2,y_2)=(1, 0)[/tex]
Therefore substitute into the above formula we have
[tex]y+1=\frac{0+1}{1-4}(x-4)[/tex]
[tex]y+1=\frac{1}{-3}(x-4)[/tex]
[tex]-3y-3=x-4[/tex]
[tex]x+3y=1[/tex]
The correct option is (A)
This is the conclusion to the answer.
