Identifying Functions and Linear Functions

What is the slope?

• m= -2/3
• m=3/2
• m=-3
• m=2

Write the equation of the line in slope intercept form given the slope m=2 and point (-3,1)

• y=2x+5
• y=x+1
• y=2x+4
• y=2x+7

Find the slope given the following points: (5,1) and (3,1)

• m=1/4
• m=0
• m=1
• m=undefined

Given the equation in point slope form, name a slope and a point on the line:  y-3=2(x+1)

• m=2, point: (1,-3)
• m=2, point (2,3)
• m=1, point (1,3)
• m=2, point (-1,3)

Transform from standard form to slope intercept form:    2x-3y=10

• y=-2x+10
• y= 2/3x-10/3
• y=-2/3x+ 10/3
• y=2/3x+10

Write in slope intercept form given the slope: m=3 and y int: -2

• y=3x-2
• y=2/3x
• y=-2x+3
