S2 A4 Graphing Linear Equations Quiz

What is an equation in point-slope form of the line shown in the graph, using the point (1, 5)?

• y - 5 = -3(x - 1)

• y - 5 = (x - 1)

• y - 1 = 2(x - 5)

• y - 1 = (x - 5)

What is an equation in point-slope form of the line that passes through the point (4, -1) and has a slope of 6?
