Write a linear equation in standard form for the line that goes through (4,2) and (8,1).
Step2247 [10]

Answer:

D. x+4y=12

Step-by-step explanation:

The given equation passes through:

(4,2) and (8,1).

The equation can be obtained using the formula;

y-y_1=m(x-x_1)

The slope is given by:

m=\frac{y_2-y_1}{x_2-x_1}

Let (x_1,y_1)=(4,2) and  (x_2,y_2)=(8,1), then we have;

m=\frac{1-2}{8-4} =-\frac{1}{4}

we now plug in the slope and the point to obtain;

y-2=-\frac{1}{4}(x-4)

We multiply through by 4 to obtain;

4(y-2)=-(x-4)

Expand using the distributive property;

4y-8=-x+4

4y+x=4+8

x+4y=12
