Write an equation of the line below
gregori [183]

Answer:

The equation of the line is:

y = 4x + 3

Step-by-step explanation:

We know that the slope-intercept of line equation is

y = mx+b

Where m is the slope and b is the y-intercept

Given the two points on a line

  • (0, 3)
  • (-2, -5)

Finding the slope between (0, 3) and (-2, -5)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-5\right)

m=\frac{-5-3}{-2-0}

m=4

We know that the y-intercept can be computed by setting x=0 and determining the corresponding y-value.

From the graph, it is clear:

at x = 0, y = 3

Thus, y-intercept = b = 3

Substituting m = 4 and b = 3 in the slope-intercept form of line equation

y = mx+b

y = 4x + 3

Therefore, the equation of the line is:

y = 4x + 3

F(x) = 9x^3 + 2x^2 - 5x + 4 and g(x) = 5x^3 - 7x + 4. What is f(x) - g(x)?
sasho [114]
F(x)= 9x^3 + 2x^2 - 5x + 4 
g(x)= 5x^3 - 7x + 4

f(x) - g(x)
9x³ + 2x² - 5x + 4 - (5x³ - 7x + 4)
9x³ + 2x² - 5x + 4 - 5x³ +7x - 4
9x³ - 5x³ + 2x² -5x + 7x + 4 - 4
4x³ + 2x² + 2x
