Write the equation of a linear function given its graph Match linear functions with their graphs Find the x-intercept of a function given its equation Find the equations of vertical and horizontal linesWe previously wrote the equation for a linear function from a graph. Now we can extend what...
EXAMPLE 1 Write an equation of a line from a graph Write an equation of the line in slope- intercept form. SOLUTION STEP 1 Find the slope. Choose two points on the graph of the line, (0, 4) and (3, –2). m 4 – (– 2) 0 – 3 = 6 – 3 = = – 2 STEP 2 Find the ...
The steps for graphing a system of linear equations are: Graph the first equation on a coordinate plane. Graph any other equations on the same plane. Look for points of intersection. If there is one point of intersection, that is a one solution system. If the graphs are parallel lin...
Massachusetts Institute of Technology professor,Gilbert Strang,explains differential equations and linear algebra which are two crucial subjects in science and engineering. This video series develops those subjects both separately and together and supplementsGil Strang's textbookon this subject. ...

Since parallel lines never cross, then there can be no intersection of these lines; that is, for a system of two linear equations that graphs as two parallel lines, there can be no solution. This is called an "inconsistent" system of equations.Independent:one intersectionone solution ...
Finally, let's graph the points of intersection by mapping the x-values of intersections to the value of the two functions that occur in the equation that was used to obtain that x-value. Since equations are symmetric (meaning that a = b ⟺ b = a), we can pick any two of the fu...
