The value of slope m is 2.
Slope
What is slope of a line?
A line's slope is how steeply it slopes from LEFT to RIGHT. No matter which two locations on the line you choose, the slope of a line is always constant (it never varies).
How to calculate the slope?
The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change.
Calculation for the slope of the given equation of line:
The graph of the line y = mx + b is given.
where,
y = y-axis coordinates
x = x-axis coordinates
m = slope
b = intercept of line at y-axis ( b = 4 in this case)
Consider any point on the line say (-1,2)
x = -1; y = 2
Put all the values in the equation of line
y = mx + b
2 = m(-1) + 4
On solving,
m = 2
Therefore, the value of slope m comes out to be 2.
