Find the slope of the equations:

3) 2x-y=10

4) 5x-2y = 10

Write a linear equation in slope intercept form of a line:

slope = - 3 and goes thru (-1, - 2)

3. 2x - y = 10

2x - 2x - y = - 2x + 10

-y = - 2x + 10

-1 - 1

y = 2x - 10

Slope: 2

4. 5x - 2y = 10

5x - 5x - 2y = - 5x + 10

-2y = - 5x + 10

-2 - 2

y = 2.5x - 5

5. y - y₁ = m (x - x₁)

y - (-2) = - 3 (x - (-1))

y + 2 = 3 (x + 1)

y + 2 = 3 (x) + 3 (1)

y + 2 = 3x + 3

- 2 - 2

y = 3x + 1
