Answer:
2
Step-by-step explanation:
The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.
7^(3x)=9 take the natural log of both sides
3xln7=ln9 divide both sides by 3ln7
x=ln9/(3ln7)
x≈0.376
