y = mx + b is just a general formula. Unless m and b are actual numbers, you can't really graph it. If m and b are real numbers, though, there are two steps to graphing the equation.
(1) Find a point on the line. The easiest point to locate is the y-intercept. Plug in zero for x, then simplify the right side of the equation to find the corresponding y value. Then plot the point (x, y) on your two-dimensional plane.
(2) Use the slope m to direct the rest of the line from that point. Write m as a fraction in its lowest form. The numerator tells you how many units up (or down, if negative) from the plotted point you should move. The denominator tells you how many units right (or left, if negative) from the plotted point you should move. After you follow the direction of both of these numbers, plot another point.
Draw a straight line that goes through both points, and you have graphed the equation!

The of a line is the set of all points x y which satisfy the equation y equals mx plus b?
graph
Y equals mX plus b rearrange to solve for b?
y = mx + b y - mx = b
How do you graph an equation written in y equals mx plus b form?
You draw a straight line through (0,b) which has a slope of m.
How do you solve y equals mx plus b solve for b?
b = y - mx.
What is the difference between y equals mx plus b and y equals mx plus c?
There is no difference; it is a matter of choice and convention as to what letter is used.
What is y equals mx plus b used for?
This is the formula for a Y intercept on a 2 dimensional graph.
Is y equals mx plus b different from f x equals mx plus b?
yes
What is the slope in y equals mx plus b?
The graph of the equation is a straight line. 'm' is its slope. 'b' is its y-intercept
Is y equals mx plus b the same thing as y equals b plus mx or do you need to convert it?
same thing. but its easy to change y=b+mx to y=mx+b
The of a line is the set of all points x y which satisfy the equation y equals mx plus b?
graph
Y equals mX plus b rearrange to solve for b?
y = mx + b y - mx = b
How do you graph an equation written in y equals mx plus b form?
You draw a straight line through (0,b) which has a slope of m.
How can you describe the graph of the equation y equals mx plus b?
It is a straight line equation whereas m is the slope and b is the y intercept.
How do you solve y equals mx plus b solve for b?
b = y - mx.
In the linear equation is the variable for the y intercept b or c ie y equals mx plus b or y equals mx plus b?
in the equation: y=mx+b , the y-intercept is represented by "b".
In the eqaution for a straight line y equals mx plus b what does the variable b represent?
b is the variable for the y-intercept, or how far up or down the graph is shifted.
What does b equal in y equals mx plus b?
sometimes it's called the "y-intercept" because when the graph is drawn, the line intersects the y-axis at b.
