Linear+Equations

What do you know about linear equations? Linear equations are equations that form a straight line when graphed. Slope? - The slope equation is m=y-y/x-x, The slope of the line is the angle at which the line is tilted. (Devon) Y-intercept? The Y intercept is where the line meets the Y axis The value of x is zero. Slope-Intercept form? the slope intercept form is y=mx+b(Devon) Writing linear equations? To write an equation given one point and the slope. Use y=mx+b for the equation and replace m with the slope. and the coordinates of the given point for x & y. solve for the y intercept b and rewrite the equation with the slope and y intercept without the coordinates. To write an equation given two points. Use the slope formula to calculate //m//. Choose any of the two given points to use in  place of //x// and //y// in //y mx b//. Replace //m// with the slope you just calculated. Solve for //b//. Rewrite the equation with the slope for //m// and the //y//-intercept for //b//. ---Devon       Use the slope formula to calculate //m//.

Linear equations are related to linear expressions. If you have 5a+2=12 thats a linear equation.A good thing to remember is that an equation has an equal sign but an expression does not.
