Question

If the point (8,k) lies on the line y=3x-5, what is the value of k?

Answer 1

k = 19

Explanation:

equation of the line is:

y = mx + b

given equation is:

y = 3x - 5

given co - ordinates are:

x, y = 8, k

thus,

substituting the values of x and y in the equation to find the value of k

k = 3(8) - 5 = 24 - 5 = 19
