The y intercept (b) is where is crosses the y axis = 5
The x intercept is where is crosses the x axis = 4
The slope is rise over run or y2 - y1/x2 - x1
m = 0 - 5/4 - 0
m = -5/4
y = mx +b
y = -5/4x + 5
Convert the fraction to a decimal:
1/25 = 0.04
Multiply by 100 to get the percent:
0.04 x 100 = 4%
The answer is 3 terms in the expression. Hope it helps!
