how do i graph G=14-25D

Question

the y intercept starts from 2-16 and x intercept 15 to 135

Answer 1

G = 14 - 25D

 

G = -25D + 14

 

This is a linear equation in the form

 

y = mx + b

 

y = G

x = D

m = -25

b = 14

 

The y intercept is point (0,b), which is (0,14).  To find the x intercept, set y = 0 and solve for x.

 

0 = -25D + 14

 

D = 14/25

 

The x intercept is the point (14/25, 0).

 

Now plot these 2 points on a Cartesian grid and run a straight line through them.  That will be your graph.

 

Question:  What do you men by "the y intercept starts from 2-16 and x intercept 15 to 135" ?  The intercepts in question are calculated directly from the given linear equation.
