#### Solutions

Chapter 1, Problem 29RCC

a.

To determine

## Write form of the equation of a line.

Expert Solution

(yy2)=m(x+x1)

### Explanation of Solution

Given information:

Write each form of the equation of a line. The point-slope form.

Calculation:

If at least one point lies on the line, the equation for line is known as point-slope form.

Given a line of slope m and a point on the line (x1,y1) the point-slope form of equation will be,

(yy2)=m(x+x1)

Hence, the point-slope form of equation is (yy2)=m(x+x1)

b.

To determine

Expert Solution

y=mx+b

### Explanation of Solution

Given information:

Write each form of the equation of a line. The slope-intercept form

Calculation:

A line has value of slope and y -intercept, the y coordinate of the point where the line crosses the yaxis is known as slope intercept form.

The slope of line m and y -intercept is b the equation for the line is,

y=mx+b

Hence, the slope-intercept form of equation is y=mx+b
