To find the equation of the line in slope-intercept form (y = mx + b), we need to use the given point (-7, -2) and the slope \( m = 4 \).
1. Start with the slope-intercept form:
\[ y = mx + b \]
2. Plug in the slope \( m = 4 \):
\[ y = 4x + b \]
3. Now we need to find \( b \) using the point (-7, -2). Substitute \( x = -7 \) and \( y = -2 \) into the equation:
\[ -2 = 4(-7) + b \]
4. Calculate \( 4(-7) \):
\[ -2 = -28 + b \]
5. Now, solve for \( b \):
\[ b = -2 + 28 \]
\[ b = 26 \]
6. Now substitute \( b \) back into the equation:
\[ y = 4x + 26 \]
So the equation of the line is \( y = 4x + 26 \).
The correct answer from your options is:
**y = 4x + 26**.
