Answer:
.
Step-by-step explanation:
All non-horizontal line in the cartesian plane intersects the 
-axis at a unique point. The 
-coordinate of that point is the 
-intercept of this line.
The -intercept of the line in this question is 
. Thus, the -coordinate of the intersection of this line and the -axis would be 
.
Like all other points on the -axis, the 
-coordinate of that intersection would be 
. Therefore, the coordinates of that intersection would be 
.
Similarly, the 
-intercept of a non-vertical line is the -coordinate of the point where that line intersects the 
-axis.
The slope-intercept form of a line is in the form 
, where 
is the slope of the line and 
is the -intercept of this line. Both 
and 
are constants.
It is given that the -intercept of the line in this question is 
. Therefore, 
. The slope-intercept equation of this line would be 
for some slope to be found.
All points 
on this line should satisfy the equation of this line. The -intercept of this line, , is a point on this line. Thus, the equation 
should hold for 
and 
. Substitute these two values into the equation and solve for the slope :
.
.
Therefore, the slope-intercept equation of this line would be:
.

Answer:
3(19x -y + 2z) is equivalent to the equation above
Answer:
= 10n
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = a₂ - a₁ = 20 - 10 = 10 , then
= 10 + 10(n - 1) = 10 + 10n - 10 = 10n
