Question

Write the equation of the linear function that passes through the points (2,1) and (5,10).

Answer 1

First, let's find the slope (m) using the two points:

m = (y2 - y1) / (x2 - x1)
m = (10 - 1) / (5 - 2)
m = 9 / 3
m = 3

Now that we have the slope, we can use the point-slope formula to find the equation of the line:

y - y1 = m(x - x1)

Using point (2,1):

y - 1 = 3(x - 2)
y - 1 = 3x - 6
y = 3x - 5

Therefore, the equation of the linear function that passes through the points (2,1) and (5,10) is y = 3x - 5.
