Step-by-Step Solution

To solve this problem, we'll proceed with the following steps:

  • Step 1: Find the slope mm.
  • Step 2: Use the slope and a point to find the yy-intercept bb.
  • Step 3: Write the linear equation.

Let's work through each step:

Step 1: Calculate the slope mm.
Using the points (0,5)(0, 5) and (1,6)(1, 6), the slope mm is calculated as follows:

m=6510=11=1 m = \frac{6 - 5}{1 - 0} = \frac{1}{1} = 1

Step 2: Use the slope (m=1m = 1) to find the yy-intercept bb.
We know from the point (0,5)(0, 5) that when x=0x = 0, y=5y = 5, which directly gives us the yy-intercept:

b=5 b = 5

Step 3: Form the equation of the line using y=mx+by = mx + b.
Substitute the found values into the equation:

y=1x+5 y = 1 \cdot x + 5

Simplifying gives:

y=x+5 y = x + 5

Thus, the equation corresponding to the function is y=x+5 y = x + 5 .

Answer

y=x+5 y=x+5
