Slope from Equations and Two Points

When given two points and asked to write an equation, what is your first step?

• Find the slope

• Find the y-intercept

• Find the x-intercept

• Write the equation

Find the equation of the line that passes through the points:

(2, 2) and (3, 4)

• y = 2x + 2

• y = -2x - 2

• y = -2x + 2

• y = 2x - 2

What is the slope-intercept form of the equation that passes through the points (1, 7) and (0, −9)?

• y = 1/2x − 9

• y = 16x − 9

• y = -1/2x − 9

• y = =16x − 9

Write an equation in slope-intercept form of the line that passes through the given points: (-4,-7) and (-6,9)

• y = 8x + 39

• y = -8x - 39

• y = -8x - 32

• y = 8x + 32

Write an equation of the line that passes through (0 , 10) and (6 , 34)

• y = 4x + 10

• y = 6x + 34

• y = 4

• y = 6x - 4

Given the two points: (0, 6) and (6,18), write the equation of the line.

• y = 2x + 6

• y = 1/2x + 6

• y = 1/3x + 6

• y = 3x + 6

Which of these represents slope-intercept form of a linear equation?

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b
