Question: 1 / 410

What is the equation of the line passing through (3, 6) and (1, 5)?

y = 3x + 5

y = 3x - 3

y = 2x + 5

To find the equation of a line, we use the formula y = mx + b.

In this question, we are given two points on the line: (3, 6) and (1, 5).

Using the formula, we can calculate the slope, m, by finding the difference in y-coordinates over the difference in x-coordinates.

So, m = (6-5)/(3-1) = 1/2.

To find the y-intercept, b, we can substitute one of the given points into the formula. We'll use (3, 6):

6 = (1/2)(3) + b

b = 6 - 3/2 = 3/2.

Therefore, the equation of the line passing through (3, 6) and (1, 5)

y = 3x + 7
