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
