I don't understand this if h(x) |1-7| 23-h(9)

The slope-intercept form is  

y

=

m

x

+

b

, where  

m

is the slope and  

b

is the y-intercept.

y

=

m

x

+

b

Find the values of  

m

and  

b

using the form  

y

=

m

x

+

b

.

m

=

0

b

=

9

The slope of the line is the value of  

m

, and the y-intercept is the value of  

b

.

Slope:  

0

y-intercept:  

9

Step-by-step explanation:

b. astronomers
