Answer:
<h2>PART A: x = 15 and y = -8</h2><h2>PART B: x = -5 and y = 3</h2>
Step-by-step explanation:
PART A:
The first equation is 
The second equation is 
Putting the value of y from (a) in the above equation, we get 
From (a) we get y = 7 - x = 7 - 15 = -8
PART B:
Here the system of equations are 
From (a) we get, 
Putting the above value of x in (b) we get, 
Hence, 
Answer:
17 units
Step-by-step explanation:
s = √15² + 8² = √289 = 17
<h2>
Answer:</h2>
First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.
<u>For slope:</u>
<u />
<u />
Slope (m) = 7
<u>For y-intercept:</u>
<u />
<u />
Y-intercept (b) = 26
Using this information, we can now create the equations for this line.

Formulas:
Slope formula: <em>y₂ - y₁/x₂ - x₁</em>
Slope-intercept form: <em>y = mx + b</em>
Point-slope form: <em>y - y₁ = m(x - x₁)</em>
<em></em>
*Note: (x₁, y₁), (x₂, y₂) = <em>2 points on the line</em>
