Y mx b equation

How do you find the slope of the equation y MX B?

In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis).

What is y mx b used for?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

What does the M stand for in Y MX B?


How do you solve y MX B on a graph?

To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value.

How do you use Y MX C equation?

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

How do you do Y MX C?

Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).

What is the slope of y =- 4?

the equation describes a horizontal line with a y-intercept of -4. as the line is horizontal, the slope is 0. The slope is 0 and the y-intercept is -4.

What is the slope of 3x 4y =- 12?

Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 12/4 = 3. Slope is -3/4 = -0.75.

Why is Y intercept B?

The reason that ‘b’ is the y-intercept is because at the ‘y-axis, x=0’. By this I mean if you look at any graph, for the point a line touches the y-axis, the x-value of a coordinate is always = 0. Knowing this, if you substitute 0 in for x in the formula you get: ‘y=mx+b’ -> ‘y=m(0)+b’.

What is a real life example of slope?

Some real life examples of slope include: in building roads one must figure out how steep the road will be. skiers/snowboarders need to consider the slopes of hills in order to judge the dangers, speeds, etc. when constructing wheelchair ramps, slope is a major consideration.
