The answer to your question should be not similar trangles
Answer:

Step-by-step explanation:
Slope-intercept form is y = mx + b.
You are given 8x + 3y = -9, so to convert this into slope-intercept form you would solve for y and rearrange the terms (if needed) to follow the format of mx + b.
Start by subtracting 8x from both sides of the equation.
3y = -9 - 8x
Divide both sides by 3 to isolate y.
y = -3 - 8/3x
Rearrange the terms so the "x" variable is first.
y = -8/3x - 3

Step-by-step explanation:
Equivalent equations are equations that have exactly the same solution. To find equivalent equations, it is best to solve them individually to find the solutions. The ones with the same solution in the end are considered equivalent equations.
