2 ways to get slope:
1.) (harder in this case) get two points, and use the formula slope = (y2 - y1) / (x2 - x1). We could choose two points and do this. If we choose x to be zero, we get y to be 600 (0,600). If we choose x to be 1, we get y to be 597 (1,597). Then plug in.
slope = (597 - 600) / (1-0) = -3/1 = -3
2.) (much easier, in this case) Alternatively, you can put the equation in the form y = mx + b, where m & b are the slope of the line and the y-intercept, respectively. Changing the given equation to this form just involves switching the order of the terms on the right, giving y = -3x + 600. The coeffient of the x term, is the slope, so the slope is -3.

Slope of any equation of line written in the form ax + by+ c = 0 is
-(coefficient of x)/coefficient of y) = -3 / 1 = -3.
The answer is -3 is the slope of the given line.

remember the equation-
y = m x + c. where y & x are the two variables and m represents the slope of ur line..
so according to ur eqn slope = - 3.
always try to reduce the eqn in the form of y = mx +c.. and accordingly corresspond ur values !!

y=600-3x
We should bring it to the form y=mx+c where m=slope,c=y intercept
y=-3x+600
m=-3=slope
600=c=y intercept(point where line cuts the y axis)

ans: -3
general equation of line: y=mx+c
base on the given equation, m (coefficient of x), which is the slope is -3

it comes down to y= -3x+600 so -3 isw sthe slope

-3 is the slope
Y = mX + b is the form, m = slope, b = intercept
in your case
Y = -3x + 600

y = 600 - 3x
y = -3x +600
Since this line is linear
the slope is always the number before x
in this case it is -3 (or down three over one)
(((((when you have other problems
it may be common to get a fraction because
you find slope by how high till the next point over how far over to the next point
you would get ?/?, so it would be a fraction)))))
(((((if you have to go up to get to the next point, the top number of your fraction is positive.
if you have to go down to get to the next point, the top number of your fraction is negative.
if you have to go to the right to get to the next point, the bottom number of you fraction is positive.
if you have to go to the left to get to the next point, the bottom number of you fraction is negative.)))))
hope this helps!!!

WHENEVER YOU FIND SUCH PROBLEM,
THEN REMEMBER THE .SLOPE-INTERCEPT FORM
Y = m X + c
TRY TO CONVERT ANY LINEAR RELATIONSHIP TO THIS FORM
[IN CASE OF THESE PROBLEMS]
SO COEFFICIENT OF X IN
.................. """"SLOPE-INTERCEPT FORM""""
ONLY IS THE SLOPE OF THE STRAIGHT LINE.
HENCE m = (-3)
