the line with slope m passing through (h,k) is y-k = m(x-h) so, for the 2nd line, you have y-3 = 4(x-1) for the first one, find the slope and then you can apply this method.

1: 2 2: 5 3: 3 4: 5 5: 4 6: 5 You'll notice that all the even numbered terms in the sequence(2nd term, 4th term, 6th term, etc.) are 5 The odd numbered terms in the sequence each increase by 1. So the next three terms should be 5, 5, 6

math help please
1st equation: y = (-1/4)x + 10 -----> slope = -1/4 2nd equation: -2x + 8y = 6 8y = 2x + 6 y = (2/8)x + 6/8 y = (1/4)x + 2/3 ----> slope = 1/4 so the lines are neither parallel , nor perpendicular.
