Question 396360: y-4=(x-5) using the point-slope form y-y1=m%28x-x1%29 Is the slope in that problem 1/1 or undefined? Written that way it kind of looks like y-4=1(x-5). Just not quite sure what the overall answer is. I need to graph the equation, so knowing that if the slope is 1/1 or undefined makes a big difference. Thanks for your time! :)

Question 396931: I'm working on the Linear Equations in my Alegbra book. I have a graph with a horizontal X line and a vertical Y line. There is a line that slopes down from left to right. My problem is asking me to find the slope, the y-intercept, and write the equation.
The line intercepts the Y line at 1, then the X line at 2. I figured the slope is -1/2 since {delta y = -2} & {delta x = 4}. I believe the y-intercept is just 2, but I'm totally questioning myself on this & have no idea how to write the equation. Can you help me please?

Question 397318: Part of the graph to a curve has equation y=x³-15/2x²+12x-18.
(a) Find the coordinates of the stationary point E.
(b) Find the coordinated of G.
G is on the X axis so Y=0.
So far I have that
y=x³-15/2x²+12x-18
so dy/dx of y=x³-15/2x²+12x-18= 3²-15x+12
Now, At SP, dy/dx=0
∴ 3x²-15x+12=0
÷3
x²-5x+4=0
(x-4)(x-1)=0
x=4 or x=1
Sub x=4 into x³-15/2x²+12x-18 and x=1 into x³-15/2x²+12x-18
4³-15/2(4)²+12(4)-18. 1³-15/2(1)+12(1)-18
64-120+48-18. 1-15/2+12-18
=-26. =-25/2

(4,-26). (1,-25/2)
Now I am compltely stuck.
Can someone please help me.
