Using equations to solve the word problem, Katherine's age is 8 years
<h3>Word Problem</h3>
Word problem are often mathematical problem that are represented in words and sometimes can be solved using an equation.
To solve this problem, we have to represent the problem using mathematical equations;
Let;
Katherine's age = x²
Alexandra = 5(x + 1)
Sum of their age = 109
5(x + 1) + x² = 109
5x + 5 + x² = 109
x² + 5x - 104 = 0
Solving for the equation; x = 8
Katherine's age is 8

Answer:
The slope of line = m = 6
The y-intercept = b = 3
Please check the attached graph below.
Step-by-step explanation:
Given the line

We know that the slope-intercept form of the line is
y = mx+b
here
now compare the slope-intercept form with the given line

so
The slope of line = m = 6
The y-intercept = b = 3
