Answer:
a = 1
Step-by-step explanation:
Given the point (a, 3) is on the line: 5x + y = 8.
Any point on the line satisfies the equation.
So, (a, 3) should satisfy the equation 5x + y = 8
Substituting x = a and y = 3, we get:
5(a) + 3 = 8
⇒ a = 1
Therefore, (1, 3) is the point on the line.

The equation of a line is given as y=0.5x+1
QA). What is the slope of the line in the graph
Ans.
The slope is given as
In the graph, the line passing through points (0,5)(-5,0)
The slope of a line:
The slope of the line in the graph is 1
QB). What is the slope of the line in the table
Ans.
The slope is given as
In the table, the line passing through points (0,3)(1,6)
The slope of a line:
The slope of the line in the table is 3
QC). What is the slope of the line in the equation
Ans.
The equation of a line is given as y=mx+c
The equation of a line is y=0.5x+1
Where m= slope
On comparing both the equation we get,
m=0.5
The slope of line in the equation is 0.5
QD). Which has the greatest rate of change
Ans.
The slope of the line in the graph is 1
The slope of the line in the table is 3
The slope of the line in the equation is 0.5
There, Rate of change is also called as the slope and it is greatest in case of the table.
