Question

Through: (5, 4), slope = 9

Answer 1

The equation of a straigth line is

y = mx + c

m = slope

from the question slope = 9

our points are (5,4)

y - y1 = m(x - x1)

x1 = 5 and y1 = 4

y - 4 = 9(x - 5)

y - 4 = 9 * x - 9 *5

y - 4 = 9x - 45

y = 9x -45 + 4

y = 9x - 41

The answer is y = 9x - 41
