Slope intercept form: y = mx + b
m = slope
b = y-intercept
The line passes through the y-axis at the point (0, -5). So, -5 is the y-intercept.
We can use the points (0, -5) and (5, 0) to solve.
Slope formula: y2-y2/x2-x1
0-(-5)/5-0)
5/5
1
The slope is 1.
Substitute these values into the equation.
y = 1x + (-5)
y = x - 5
Therefore, the answer is [ y = x - 5 ]
Best of Luck!

<u>Algebra I</u>
- Terms/Coefficients
- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = x - 16
5y = 2x - 56
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em>:                                                                                                5(x - 16) = 2x - 56
- Distribute 5:                                                                                                     5x - 80 = 2x - 56
- [Subtraction Property of Equality] Subtract 2x on both sides:                     3x - 80 = -56
- [Addition Property of Equality] Add 80 on both sides:                                3x = 24
- [Division Property of Equality] Divide 3 on both sides:                                x = 8
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation:                                                                               y = x - 16
- Substitute in <em>x</em>:                                                                                                y = 8 - 16
- Subtract:                                                                                                          y = -8
 
        
             
        
        
        
Answer:
