What is an equation of the line that passes through the points (4,-6) and (8,-4)

qaws [65]

Answer:

$y = \frac{1}{2} x - 8$

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient (also known as slope) and c is the y-intercept (the point through which the line cuts through the y-axis).

$\boxed{gradient = \frac{y1 - y2}{x1 - x2} }$

Using the gradient formula above,

$m = \frac{ -4 - ( - 6)}{8 - 4} \\ m = \frac{ - 4 + 6}{4} \\ m = \frac{2}{4} \\ m = \frac{1}{2}$

Substitute the value of m into the equation:

y= ½x +c

To find the value of c, substitute a pair of coordinates.

When x=4, y= -6,

-6= ½(4) +c

-6= 2 +c

c= -6 -2 (-2 on both sides)

c= -8 (simplify)

Thus, the equation of the line is y= ½x -8.

Whats the correct answer?

GarryVolchara [31]

Answer:

Actually the answer is "A"

this is a very strange way to present a problem...

this issue her is that $(x^{a}) ^{b} = x^{a*b}$

so you need 1/3 * 3 in the answer... none of them have 1/3 * 3

BUT !!!!! 1/3 + 1/3 + 1/3 is the same as 1/3 * 3 So "A" is the solution
