Answer:


\boxed{\bf{y=4x+3}}

Explanation:

We are given the following information:

  • the line passes through (-2,-5)
  • the line has a slope of 4

Use the point-slope formula:


\bf{y-y_1=m(x-x_1)}

Substitute the values.


\bf{y-(-5)=4(x-(-2)}

simplify:


\bf{y+5=4(x+2)}

use the distributive property to disttribute 4.


\bf{y+5=4x+8}

subtract 5 from both sides:


\bf{y=4x+8-5}

simplify!


\boxed{\bf{y=4x+3}}

Answer:

y = 4x + 3

Explanation:

Slope intercept form: y = mx + b

Given: Point (-2, -5), Slope (m) = 4

1. Substitute the slope intercept form with your given variables:

New equation: -5 = (4 x -2) + b

2. Simplify the right side

New Equation: -5 = -8 + b

3. Isolate b by adding 8 on both sides of the equation.

New equation: b = 3

Now, we know that b (y-intercept) = 3

4. Rewrite your equation:

New equation (final answer): y = 4x + 3
