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;

$4y-8=-x+4$

$4y+x=4+8$

$x+4y=12$

Solve the equation by using the basic properties of logarithms. log(2x)=3

Scilla [17]

If no base is mentioned, asssume base 10

remember
$log_a(b)=c$ translates to $a^c=b$
so
since no base mentioned, assume base 10

$log_{10}(2x)=3$ translates to $10^3=2x$ then
1000=2x
divide both sides by 2,
500=x
