Find x and y in to the diagram​

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 - )

Y= 4x + 3 y = - 1 4 x - 5 what is the best description for the lines represented by the equations?

Two different points r and y are dilated from s with a scale factor 3/4, andry equal 15. use the dilation theorm to describe two facts that are known about ry
