Answer :
Answer:
Step-by-step explanation:
y = mx + b is an equation or formula, not a "problem."
Starting from y = mx + b, solve for m:
1) subtract b from both sides, obtaining y - b = mx
2) Divide both sides of this equation by x:
y - b
m = ----------
x
The expression for the slope is m = (y - b)/x if the equation of the line is y = mx + b.
What is a straight line?
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have an equation for the line:
y = mx + b
To solve for m make a subject as m:
mx = y - b
m = (y - b)/x
Thus, the expression for the slope is m = (y - b)/x if the equation of the line is y = mx + b.
