Answer:
x = -639 / 4819 (x = -0.1326 [rounded])
Step-by-step explanation:
7x - 7/79 = 68x + 8
{subtract 7x from both sides to begin to isolate x}
7x - 7/79 = 68x + 8
-7x - 7x
- 7/79 = 61x + 8
{subtract 8 from both sides to isolate x}
- 7/79 = 61x + 8
- 8 -8
{8 = 632/79}
- 639 / 79 = 61x
{divide both sides by 61 to isolate x}
-639 / 79 = 61x
÷ 61 ÷61 ÷

-639 / 4819 = x
(-639/4819 ≈ -0.1326 [rounded] )

Given:
The inequality is:
To find:
The y-intercept, slope and type of line (solid or dotted).
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept.
We have,
The relation equation is:
...(ii)
On comparing (i) and (ii), we get
It means the slope is 5 and the y-intercept is 3.
The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.
Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.
