Question

What is the slope of the line represented by the equation y=-3x+1?

Answer 1

Start at (0,1) and go up 3 and over 1 to (1,4) connect the points.
Step-by-step explanation:
y
=
3
x
+
1
is in the slope intercept form
y
=
m
x
+
b

m = the slope in this case 3
b = the y intercept in this case 1.
Think of b the y intercept as the beginning this is where to start the graph.
So start with (0,1) the y intercept and make the first point at (0,1)
Think of m ( the slope) as the mountain slope, This is the angle of the slope of the line
So in this case go up three on the y axis and over 1 on the x axis.
make the next point at 1 + 3 = 4 for the y value and 0 + 1 = 1 for the x value. Make the next point at ( 1, 4)
Now connect the points. creating the line

Answer 2

When a line is represented in the slope intercept formula as in the question you must remember that it is always set up like so...

y = mx + b

m is the slope and b is the y-intercept of the line

Since in the equation y = -3x + 1 the m is -3 then the slope is -3

Hope this helped!
