What is the a nswer to 5(r-11)=2(r-4)-6

1 answer:

6 0

5 (r - 11) = 2 (r - 4) - 6 Use the Distributive Property on both sides
5r - 55 = 2r - 8 - 6 Combine like terms (-8 and - 6)
5r - 55 = 2r - 14 Subtract 2r from both sides
3r - 55 = -14 Add 55 to both sides
3r = 41 Divide both sides by 3
r = 14 $\frac{2}{3}$

A line passes through the given points. Write an equation for the line in point-slope form. Then rewrite the equation in slope-i

Andre45 [30]

Answer:

The answer to your question is a) y - 2 = -5(x - 3)

b) y = -5x + 17

Step-by-step explanation:

Data

A (1, 12)

B (3, 2)

Process

1.- Find the slope

Formula

$m = \frac{y2 - y1}{x2 - x1}$

Substitution

$m = \frac{2 - 12}{3 - 1} = \frac{-10}{2} = - 5$

2.- Find the equation in point slope form

Equation

y - y1 = m(x - x1)

Substitution and equation

y - 2 = -5(x - 3)

3.- Find the slope-intercept form

Expand the point slope form

y - 2 = -5x + 15

Simplify

y = -5x + 15 + 2

Equation

y = -5x + 17
