Final answer:
The equation of the line with a slope of 3 passing through the point (.2,5) is y = 3x + 4.4.
Step-by-step explanation:
The equation of the line that has a slope of 3 and passes through the point (0.2,5) can be found using the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope. Plugging in the values, we have y - 5 = 3(x - 0.2). Expanding this equation gives y - 5 = 3x - 0.6. Solving for y, we get y = 3x + 4.4. Therefore, the equation of the line is y = 3x + 4.4.
