Graph the equation y=kx+1 if it is known that the point M belongs to it: a M(1, 3)

Question

Graph the equation y=kx+1 if it is known that the point M belongs to it:

 Chapter Reference

a

M(1, 3)

Answer 1

y = kx + 1

(1,3)

3 = k(1) + 1

2 = 1k

k = 2

Answer 2

Since (1,3) is on the graph, 3 = k + 1 and k = 2

Therefore, the graph is a straight line with positive slope.(2) and and x-intercept 1.
