@broderick365 Let's have a point (x, y) on the line. So we have two points (x, y) and (1, 8)
Can you find the slope using these two points?

5/2

ash2326 · Answer

I mean, don't see the slope given. Assume it's not there, how would you find it?

anonymous · Answer

idk

ash2326 · Answer

Do you understand what it means by slope?

anonymous · Answer

yes

ash2326 · Answer

What does it mean?

anonymous · Answer

to find the slope of the line

ash2326 · Answer

Ok, I'll explain, slope of a line is the change in y with respect to x. That's more of a mathematical definition.
It represents how a line rises or falls as x increases, if slope is positive line rises as x increases

|dw:1375893818175:dw|

ash2326 · Answer

Now if slope is negative then line will fall as x increases
|dw:1375893946469:dw|

anonymous · Answer

yses can we speed this up

ash2326 · Answer

We can use any two points on a line to find its slope, let's say we have two points (x1, y1) and (x2, y2)
Slope ( say m) is given by
$$m=\frac{y2-y1}{x2-x1}$$

Can you use this to frame an equation for our problem?
