What is the slope of a line parallel to the line whose equation is x + 2y = 10. Fully simplify your answer.

The required slope is equal to -1/2.

Step-by-step explanation:

The given equation of line is :

x + 2y = 10

A line parallel to this line has the same slope. To determine the slope, solve for  y  to change the equation to slope-intercept form:

y = mx+b .....(1)

2y = 10 -x

Dividing both sides by 2.

....(2)

Comparing equations (1) and (2),

m = -1/2

Hence, the required slope is equal to -1/2.

the answer is that it is true
