F(x) = 3x^2
g(x) = 4x^3

(f * g)(x) = 3x^2 * 4x^3 = 12x^(2 + 3) = 12x^5

the degree of (f * g)(x) is 5 <==

Answer:

y = -\frac{1}{4}x

Step-by-step explanation:

1. The slope-intercept form of a linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.

2. To find the slope, let's take the two points (0,0) and (-40,10). After that, let's plug in the values to their corresponding variable in the formula: \frac{y_2-y_1}{x_2-x_1}

  • \frac{10-0}{-40-0}
  • \frac{10}{-40}
  • -\frac{1}{4}

3. Since we now know our slope, the equation looks like this so far: y = -\frac{1}{4}x + b.

4. Because b is the y-intercept, b = 0 because the line intersects the y-axis at (0,0).

5. Now that we have the values of m and b, we plug in them to get the equation of: y=-\frac{1}{4}x
