CCSS.8.F.A.1

Write an equation of the line passing through the points (4,7) and (5,-2). 

• y = -9x + 43
• y = 9x  - 43
• y = -9x + 3

CCSS.HSA.CED.A.2

Write the equation of a line in point-slope form that passes through the point (-4,5) with a slope of -5/2. 

• y + 5 = 5/2(x-4)
• y - 5 = -5/2(x+4)
• y - 5 = 5/2(x - 4)
• y - 5 = -5/2(x - 4)
