Sorry for tje late answer but it is 150 * 0.08^x
Answer:
y = -5x + 8
Step-by-step explanation:
Equation of a line: y = mx + b
x = slope
b = y-intercept or starting point
Slope = y^2 - y^2/x^2 - x^1
Slope = -12 - 43/4 - (-7)
Slope = -55/11
Slope = -5
b = y - y^1 = m(x - x^1)
b = y - 43 = -5(x - (-7))
b = y - 43 = -5x - 35
Add 43 to both sides
