Slope= (B≠0) x 4. Equations of Straight Lines (a) How to find the slope of a straight line? Finding slopeEasy Memory Tips: Slope-intercept formy = mx + c y = mx + c When the equation of straight y-intercept Slope of straight line line is transformed into slope- intercept form, the coefficient of General formAx + By + C= 0 Ax + By + C= 0 x in theequation is the slope of the straight line. -By =Ax + C -By =Ax + C In slope-intercept form,the -B -B y = A x + C constant term of the equation is the y-intercept of the straight Slope of straight line y-intercept line.
Slope= (B≠0) y-intercept=(B≠0) When the equation of straight y-intercept Slope of straight line line is transformed into slope- intercept form, the coefficient of General formAx + By + C= 0 x in theequation is the slope of the straight line. -By =Ax + C -By =Ax + C In slope-intercept form,the x y = constant term of the equation is the y-intercept of the straight Slope of straight line y-intercept line. 4. Equations of Straight Lines (b) How to find the y-intercept of a straight line? (a) How to find the slope of a straight line? Finding slopeEasy Memory Tips: Slope-intercept formy = mx + c Finding y-interceptEasy Memory Tips: Method I:
y-intercept=(B≠0) y-intercept y = When it is required to find both the slope and the y-intercept or the equation of straight line is in slope-intercept form, use Method I to get the y-intercept. When the equation of straight line is in general form and it is required to find they-intercept only, it is better to use Method II to get the y-intercept. y-intercept= In slope-intercept form,the constant term of the equation is the y-intercept of the straight line. 4. Equations of Straight Lines (b) How to find the y-intercept of a straight line? Find the y-intercept of the straight line Slope-intercept form y = mx + c Finding y-interceptEasy Memory Tips: Ax + By + C= 0. Substitutex= 0 into Ax + By + C= 0, Method I: Method II: Substitute x = 0 into the By + C= 0 equation to find the value of y.
x-intercept=(A≠0) x = x-intercept= 4. Equations of Straight Lines (c) How to find the x-intercept of a straight line? Finding x-interceptEasy Memory Tips: Find the x-intercept of the straight line Ax + By + C= 0. Substitute y = 0 into the Substitutey = 0 into Ax + By + C= 0, equation to find the value of x. Ax + C= 0
