Forms of Linear Equations

Key Questions

  • The standard form of a linear equation is: #color(red)(A)x + color(blue)(B)y = color(green)(C)#

    Where, if at all possible, #color(red)(A)#, #color(blue)(B)#, and #color(green)(C)#are integers, and A is non-negative, and, A, B, and C have no common factors other than 1

    The slope of an equation in standard form is: #m = -color(red)(A)/color(blue)(B)#

    The #y#-intercept of an equation in standard form is: #color(green)(C)/color(blue)(B)#

  • Answer:

    I have heard of four

    Explanation:

    Slope-intercept form: #y=mx+b#, where #m# is the slope and #b# is the y-intercept

    Standard form: #ax+by=c#

    Point-slope form: #y-y_1=m(x-x_1)#, where #m# is the slope and #(x_1, y_1)# is a point on the line

    Intercept form: #x/a+y/b=1#, where #a# is the x-intercept and #b# is the y-intercept
