Thanks!!

Write an equation of the line satisfying the given conditions. Parallel to the line y=-5x-6 and a y-intercept of -2. Would it be: y=-5x-2 The slope stays the same due to it being parallel and the only thing that changes is the y-intercept and that would be the -2. Am I correct?

Algebra
Okay. I had went ahead and done this. I found out that a negative slope the line goes down left to right and a positive slope got up left to right. Thanks for the help.

I am having to graph this linear equation. y=-2x+4 This is what I know. The y-intercept is 4 and the slope is -2. So I would start at the y-axis at 4, then would I go down 2 units and over to left one or go up 2 units and to the right one. Dont know how to graph it.

Equation: 2x/5-x/3=5 (2x/5 and x/3 is a fraction) I know that you are suppose to combine like terms, like x, but don't know what I need to do, since they are fractions. Help please.

A car enters a interstate highway 15 mi north of the city. The car travels due north at an avrage speed of 62.5 mph. Write an equation to model the car's distance from the city after traveling for h hours.

Okay. I thought this was true, but was confused. Thanks for clearing this up for me. And also for a fast response.

Solve this equation: -4x^2=0 Lost what to do to solve this equation, especially with the exponent of 2.

Math
Ok. Can you explain how this is so? Just so I know and understand.

Write a brief scenario that can modeled with a linear equation. AND Summarize a situation modeled by a quadratic equation. I am completly lost with these two questions. I understand the difference between these two functins but don't know how to come up with a scenario or ...
