Answer:
y = -4x + 5
Explanation:
Linear Formula: y = mx + b
b: The line touches the Y-axis at the fifth unit (0,5)
m: Using the rise-over-run method; the line can be seen going from the coordinates (0,5) to (1,1). Moving from (0,5) to (1,1), you move the plot 4 units downwards and 1 unit to the right; 4/1 = 4. Since the line is sloping downward, the line entire slope value would be -4
With m = -4 and b = 5; your equation is y = -4x + 5
