Use the slope formula<span> to find the slope. Use the slope (that you found in the step above) and one of the </span>points<span> to find the y-intercept. (Using y = mx+b, substitute x, y, and the slope (m) and </span>solve<span> the</span>equation<span> for b.) </span>Write<span> the </span>equation<span> in slope intercept</span>form<span> using the slope and y-intercept</span>
What we have here is called INTERSECTING CHORDS IN A CIRCLE.
The equation is:
10 times x = 7 times 7
10x = 49
x = 49/10
x = 4.9
Yes the lines are parallel
