The formula for calculating slope is expressed as

slope = (y2 - y1)/(x2 - x1)

From the information given,

x1 = 5, y1 = - 2

x2 = 6, y2= - 5

Slope = (- 5 - - 2)/(6 - 5) = (- 5 + 2)/1

Slope = - 3

The equation of a line in the point slope form is expressed as

y - y1 = m(x - x1)

where

m = slope = - 3

The equation of the line is

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

y + 2 = - 3(x - 5)

When x = 0,

y + 2 = - 3(0 - 5) = - 3 * - 5 = 15

y = 15 - 2

y = 13

When x = 1,

y + 2 = - 3(1 - 5) = - 3 * - 4 = 12

y = 12 - 2

y = 10

Thus, two other points are

(0, 13)

(1, 10)
