Question 369055: Would someone help me with these questions?

1. The line passing through (7,y) and (1,0) is parallel to the joining (4,4) and (-2,1). Find Y


2.Write the point slope form of the line's equation satisfying the given condition. Then use the point slope form of the equation to write the slope intercept form. Slope m=2 passing through(7,4))

Hi,

1) line passing through (7,y) and (1,0)parallel to linethe joining (4,4) and (-2,1). 

m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29

(4,4) and (-2,1)

m = (1-4)/(-2-4) = -3/-6 = 1/2

line passing through (7,y) and (1,0) with slope = 1/2

Note: x increased by 6, therefore y must increase by 3 (1/2 = 3/6)

y = 3



2) y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29

Slope m = 2 passing through(7,4))

y - 4 = 2(x - 7)

y - 4 = 2x - 14

y = 2x -10
