Need quick help if you know quick answers to these reply please

1.A line has slope 4 and it passes through point M (1,5). Write the equation of the line in the form.

y= mx + b

2.Find the point of the intersection of the linear system without graphing.

A) y = 2x -3

B) y = 3x -5

3. Find the greatest common factor

5x²-20x+25

3. Expand each of the binomials to standard form

A) y=(x + 3)(x + 5) B)y = (x-4)(x +4)

4. Lighthouse: The angle of depression from the top of a lighthouse to a bout is 34°. The lighthouse is 30 metres tall. how far is the boat from the base of the lighthouse?
