The given equation is $y = -2_5x + 1$. It appears that the underscore between the "2" and "5" might be a typo. If you're asking about the line $y = -\frac{2}{5}x + 1$, here's how to find the slope and the y-intercept:

1. Slope:

The slope of a line in the form $y = mx + b$ is the coefficient of $x$, which is $m$.

In this case, $m = -\frac{2}{5}$.

So, the slope is $-\frac{2}{5}$.

2. Y-intercept:

The y-intercept is the constant term, $b$, which is the value of $y$ when $x = 0$.

Here, $b = 1$.

So, the y-intercept is 1 (or the point $(0, 1)$).

Would you like further details on how to graph this or any other clarifications?

Here are 5 questions to consider:

1. What is the effect of changing the slope on the line?
2. How does a positive slope compare to a negative slope?
3. What happens if the y-intercept is negative?
4. How can you rewrite this equation in standard form?
5. Can you calculate the slope between two points on a line?

Tip: A steeper slope means the line rises or falls more quickly as you move along the x-axis.
