Question

Distinguish differences and similarities between slope intercept form and point slope form ohysics

Answer 1

Differences:

point slope form of line:

(a) equation is $(y-y_1)=m(x-x_1)$

where m is slope and (x1,y1) is a point

(b)This equation of line can be determined when two points are given

(x1, y1) and (x2,y2)

slope intercept form of line:

(a) equation is $y=mx+b$

where m is a slope

b is y-intercept

(b)This equation of line can be determined when y-intercept and slope are given

Similarilties:

(a) both are equation of straight line

(b) slope is always constant in both
