# 4 1 practice graphing equations in slope intercept form

GRAPHING by SLOPE-INTERCEPT METHOD If the equation is given in the form y = mx + b, then the constant term, which is b, is the y intercept, and the coefficient of x, which is m, is the slope of the straight line. The easiest way to graph such a line, is to plot the y-intercept first. The S-I equation is y = mx + b, where "m" is the slope, and "b" is the y-intercept. Y must be isolated in order to do this. Example: 2x + y = 4 Subtract 2x from both sides: 2x - 2x + y = 4 - 2x y = -2x + 4 Sometimes you have to divide by the coefficient to isolate y. Rewriting Linear Equations in Slope-Intercept Form Jefferson Davis Learning Center, Sandra Peterson Rewrite each equation in slope-intercept form and state the slope and y-intercept of the line. slope-intercept form slope y-intercept 1. 3x+y =5 1. y =−3x+5 −3 ()0,5 2. 4x+2y =10 2. y =−2x+5 −2 ()0,5 3. Use The Slope And Y-intercept When Drawing The Line. Use the slope and y-intercept when drawing the line.Let us learn more about y-intercept, the definition of y-intercept and the meaning of y-intercept, definition of y-intercept, example of y-intercept, and explore y-intercept calculator. Check out the interactive simulations to know more about the lesson and try your hand at solving a few interesting practice questions at the end of the page. Slope Intercept Form. The equation of a straight line can be given in different forms. Two benefits of the slope intercept form is that both the slope (m) and the y-intercept (b ) are immediately obvious. Let us convert the example above from standard form to slope intercept form
