Algebra (w#5) and Graph from linear equations (w#8)

What is the equation of a line with a slope of 2 and a y-intercept of -5?

• y = 5x - 2

• y = 2x - 5

• y = -2x - 5

• y = 2x + 5

Convert the equation of the line

y + 5 = -3(x - 6)

into slope intercept form.

• y = -3x - 23

• y = -3x - 13

• y = -3x - 11

• y = -3x + 13

What are the x- and y- intercepts, respectively, on this graph?

• (0,5), (0,5)
• (5,0), (5,0)
