For 1
Twice a number means
A number used two times
Is that number was x
What do we do to x
Using the slope-intercept form, the slope is 3 3 . To find an equation that is parallel<span>to </span>y=3x−2 y<span> = 3 x - </span>2<span> , the slopes must be equal. Using the slope of the equation, find the </span>parallel line<span> using the point-slope formula. Find the value of b b using the formula for the equation of a </span>line<span>.</span>
For this case we must find a linear equation of the form:
Where,
m: slope of the line
b: cutting point with vertical axis.
For the slope we have the following equation:
Substituting values we have:
We observe that the slope of the line is not defined.
Therefore, the line is vertical.
Thus, the equation of the line is given by:
Answer:
The equation of the line is given by:
