Parallel lines have the same a slope.

The slope-intercept form:

$y=mx+b$

A line passes through the points (-2, -4) and (3, 5).

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{5-(-4)}{3-(-2)}=\dfrac{5+4}{3+2}=\dfrac{9}{5}$

Substitute to the slope-intercept form:

Answer: $y=\dfrac{9}{5}x+b,\ b\in\mathbb{R}$

Answer:

y = - 2x - 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line

m = $\frac{-4-0}{0-(-2)}$ = $\frac{-4}{0+2}$ = $\frac{-4}{2}$ = - 2

the line crosses the y- axis at (0, - 4 ) ⇒ c = - 4

y = - 2x - 4 ← equation of line

F(x) = 9-3x g(x) = 5x-7 Find f(x)+g(x).

Bezzdna [24]

Answer:

In the problem, the sum of the two functions is 2x + 2

Step-by-step explanation:

For this problem, we have to add together f(x) and g(x).

f(x) = 9 - 3x

g(x) = 5x - 7

(f + g)(x) = (9 - 3x) + (5x - 7)

Combine like terms.

(f + g)(x) = 2x + 2

So, when you combine the two functions together, you will get 2x + 2.

Is 2(x+5) factored?

Yes, it is! The unfactored version of that expression would be 2x+10.
