Question 464002: Write an equation of the line then graph the line with a slope of -5 and y-intercept (0,3).
The equation I came up with is y=-5x+3. Is this correct?
Graph:
I know where to plot the y-intercept of (0,3) but not sure how to graph the slope of -5. Would it be -5/1 (Rise/Run) and if so, would it be 5 down and 1 to the right?

Question 464005: Hello my name is Gabriella,
The problem that I need help figuring out whether it was executed right is
For each equation, find the slope of each equation. If the slope is undefined, state this. The problem is 5x-2=2x-7.
I have tried finding the slope of this equation by adding the like terms 5x+2x=7x and -2+-7=5.
I subtracted 5 from both sides and was left with 2x=0, I then divided 2 on both sides and was left with 0.
Is this equation undefined
