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 nonnegative, and, A, B, and C have no common factors other than 1The 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:
Slopeintercept form:
#y=mx+b# , where#m# is the slope and#b# is the yinterceptStandard form:
#ax+by=c# Pointslope form:
#yy_1=m(xx_1)# , where#m# is the slope and#(x_1, y_1)# is a point on the lineIntercept form:
#x/a+y/b=1# , where#a# is the xintercept and#b# is the yintercept
