Keystone Algebra I

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)

Write an equation that is parallel to y = 3x + 5 and going thru (2,5).

• y = 3x + 1

• y = 3x - 1

• y = -3x -1

• y = -3x + 1

Solve: (Elimination)
2x - y = 13
3x + y = 2

• (-19, -3)

• (3, -7)

• (5, -3)

• (9, 5)
