Question 270083: Graph the following linear equation by finding x- and y-intercepts.
2x – 4y = -8
Describe the graph verbally by showing the calculation of the two intercepts and giving the ordered pair for each. Describe the line you have graphed. The description should include the quadrants through which the line passes, and the direction the line leans (forward or backward).

Question 275511: Find the equation of the line tangent to the circle at the indicated point.
x^2 + y^2 = 25
(3,4)
I believe the circle has a center of (0,0) and a radius of 5. I do know that the point (3,4) is perpendicular to the radius of the circle.
I am not sure how to plug the line tanget points into this and find an equation for that tangent line though.
