Y=2x+2 the equation that represent the line
Answer:
18
Step-by-step explanation:
The point-slope equation of the line is 
Step-by-step explanation:
The form of the point-slope equation is
, where
- m is the lope of the line
is a point lies on the line
The slope of a line
, where
and
are two points on the line
∵ The line through (2 , 3) and (7 , 4)
∴
= 2 and
= 7
∴
= 3 and
= 4
- Substitute these value in the rule of the slope
∵ 
∴ the slope of the line is 
Let us substitute the value of the slope and the coordinates of point
in the form of the equation
∵ 
∵
= 2 and
= 3
∵ 
∴ 
The point-slope equation of the line is

Answer:
no solution
Step-by-step explanation:
The equations describe parallel lines. There are no values of x and y that will satisfy both equations.
In standard form, the two equations are ...
3x +7y = 21
3x +7y = -42 . . . . . with positive leading coefficient
If (x, y) values satisfy the first equation, they cannot satisfy the second equation, and vice versa.
