Answer:

1/3

Step-by-step explanation:

Simplify the following:

1 - 2/3

Put 1 - 2/3 over the common denominator 3. 1 - 2/3 = 3/3 - 2/3:

3/3 - 2/3

3/3 - 2/3 = (3 - 2)/3:

(3 - 2)/3

3 - 2 = 1:

Math 8: Linear Functions, Part 2

Studentka2010 [4]

Answer:

$\boxed{\text{1. y + 5 = -4(x - 3); \qquad 2. y - 8 = x + 1}}$

Step-by-step explanation:

Question 1

The point-slope formula for a straight line is

y – y₁ = m(x – x₁)

x₁ = 3; y₁ = -5; m = -4

Substitute the values

$\boxed{\textbf{y + 5 = -4(x - 3)}}$

The diagram shows the graph of equation 1 (red) with slope -4 passing through (3,-5).

Question 2

x₁ = -1; y₁ = 8; m = 1

Substitute the values

$\boxed{\textbf{y - 8 = x + 1}}$

The diagram shows the graph of equation 2 (green) with slope 1 passing through (-1,8).

Graph the equation by plotting three points. If all three are correct the line will appear -3y=-2x-6

Pachacha [2.7K]

Three possible points are:
(-3, 0)
(0, 2)
(3, 4)

To find any points, simply select any value for x. Input that value, then find the corresponding y-value.

For example, if x = 0, then:

-3y = -2(0) - 6
-3y = -6
y = 2
