What is the slope of a line that passes through two points (2,c) and (5,c)
1 answer:
Answer:
The slope of the line is zero
Step-by-step explanation:
The slope is simply a measure of the degree of tilt that a straight line has in a coordinate system.
To get the slope between two coordinates, We can make use of this formula.
Where m = slope of the line
x2 = 5
x1 = 2
y2 = c
y1 = c
Any number that divides zero will give 0
From this, we can see that the slope of the line is = 0

Answer:
a₁₅ = 30
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
Given a₅ = 10 and a₁₀ = 20 , then
a₁ + 4d = 10 → (1)
a₁ + 9d = 20 → (2)
Subtract (1) from (2) term by term to eliminate a₁
5d = 10 ( divide both sides by 5 )
d = 2
Substitute d = 2 into (1) and solve for a₁
a₁ + 4(2) = 10
a₁ + 8 = 10 ( subtract 8 from both sides )
a₁ = 2
Then
a₁₅ = 2 + (14 × 2) = 2 + 28 = 30
