The equation for a straight line is y = mx+b whereas m is the slope and b is the y intercept

For example: y = 3x+9 which means that 3 is the slope and 9 is the y intercept

Is a linear equation the same as a function?

No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.


What is an example of a linear equation?

The slope-intercept form of a linear equation is y = mx + b where m = slope and b = the y-intercept.


What is the difference between a linear equation and an quadratic equation?

A linear equation, when graphed, is always a line. A quadratic is a curve. Also, linear equations are of the form y=mx+b where m and b are arbitrary constants and quadratics are y=(x^2) +mx +b where m and b are arbitrary constants.


Is linear function the same as linear equations?

No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.


How do you identify a slope given in a linear equation?

To identify the slope in a linear equation, rearrange the equation into the form y = mx + b. The term m is the slope.


What does the equation for a linear relationship stand for?

y=mx+b is the equation for a linear relationship. y= the dependant variable m= the slope of the line x= the independent variable b= the y-intercept


How do you write the function form of the linear equation?

f(x) = mx +b. m and b are arbitrary constants.


What is the slope-intercept form of linear equation?

y = mx + b Where m is the slope and b is the intercept on the y-axis.


How do you do a linear graph?

A linear line is just a straight line. To graph it, you can use this equation: y=mx+b where m = the slope of the line, and b = the y-intercept of the line, in other words, where the line crosses the y-axis.


How do you make and equation on a line in a graph?

The equation for the slope of a linear equation is Y=Mx+b, where m is the slope of the line, (Rise over run) and where B is the Y-intercept. (Where it crosses the Y axis)


Is the x intercept the same as the slope?

No. In a linear equation, y = mx + b, the slope is m, and the x intercept is where mx + b = 0.


Give the slope-intercept form of a linear equation?

y = mx + b b is where the line crosses the y axis. m is the slope
