Answer:

y = -4x + 5

Explanation:

Equation of the line can be written as y = mx + b (slope-intercept form)

Where m = slope and b = y-intercept of the line.

Let's find m and b of the line

Slope (m) using the points (1, 1) and (0, 5),

Slope (m) = change in y/change in x

m = (5 - 1)/(0 - 1) = 4/-1

m = -4

Find b:

b = the point where the line cuts the y-axis = 5 (y-intercept)

To write the equation substitute m = -4 and b = 5 into y = mx + b

y = -4x + 5
