How many equal line segments are needed to make 6 triangles

Choose the correct slope of the line that passes through the points (1, -3) and (3, -5)

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )

What percent of 18 is 24? and plz explain thx.
