Answer:

Step-by-step explanation:
Given

Required
Fill in the gap to produce the product of linear expressions

Split to 2

Factorize the first bracket

Represent the _ with X

Factorize the second bracket

To result in a linear expression, then the following condition must be satisfied;

Subtract b from both sides


Multiply both sides by 5


Substitute -15 for X in 




The two linear expressions are
and 
Their product will result in 
<em>Hence, the constant is -15</em>

Answer:

Step-by-step explanation:
The slope-intercept form of equation of a linear function:

m - slope
b - y-intercept
We have the slope m = 4/5 and the y-intercept b = -6. Substitute:
