Linear Equations in PointSlope Form
Key Questions

Answer:
1) pointslope form
2) slope intercept formExplanation:
1)
#y−b=m(x−a)#
m = slope
(a, b) A point that the line passes through2)
#y=mx+b#
m = slope
b = yintercept 
Answer:
Explanation below:
Explanation:
Let's use this example from http://www.purplemath.com/modules/strtlneq2.htm to help you understand how to graph pointslope form equations:
#m = 4# ,#x_1 = –1# , and#y_1 = –6# are given.Formula:
#y – y_1 = m(x – x_1)# Plugin your variables:
#y – (–6) = (4)(x – (–1))# Simplify. Two negatives make a positive:
#y + 6 = 4(x + 1)# Distribute 4 to x and 1. Simplify.
#y + 6 = 4x + 4# Subtract 6 from both sides.
#y = 4x – 2# graph{y=4x2 [12.66, 12.65, 7.7, 4.96]}

To find the equation of a line having a point
#P(x_p,y_p)# and with the slope#m# , this formula can be used:#yy_p=m(xx_p)# .E.G.:
Find the line that passes from P(2,3) with the slope of 4:
#y+3=4(x2)rArry=4x11# .graph{4x11 [10, 10, 5, 5]}.
