5/4 Slope intercept, standard, point-slope forms

• Slope Intercept Form

• Point-Slope Form

• Standard Form

What is Standard form of a linear equation?

• y - y1 = m(x - x1)

• y = mx + b

• ax + by = c

• Dis not right...

Write an equation in Slope-Intercept Form of the graph pictured.

• y = 3/2x + 1

• y = -3/2x + 1

• y = 2/3x + 1

• y = -2/3x + 1

Write an equation in Slope-Intercept form given the following information: slope = 4/3 ; y-intercept = -2. Write your answer without spaces.

Name the x- and y-intercepts for the equation:
5x - 3y = 15

• (3, 0) and (0, -5)
• (0, 3) and (-5, 0)
• (5, 15) and (15, 3)
• (0, -3) and (5, 0)

Write the slope intercept form of the equation x - 3y = 6

• y = -x - 2

• y = x + 2

• y = 1/3x - 2

• y = -1/3x + 2

Write the equation of the line in Point-Slope form that goes through the point (10,5) and has a slope of -3

• y - 5 = -3(x - 10)
• y= -3x + 35
• y + 5= -3(x + 10)
• y= -3x - 35

Select the correct answer.

• No.

• Not this one.

• Correct Answer.

• Again, not this one.

For the equation
y - 3 = 2(x + 4),
the line has a slope of 2 and contains what point?

• (-4, 3)
• (3, -4)
• (-3, -4)
• (-4, -3)

Convert to slope-int

• y= -1/4x-3/4
• y=-1/4x+3/4
• y=3/4x-1/4
• y=-3/4x+1/4
