$$m=$$
$y$-intercept:

Step 1 ：The problem is asking for the slope (m) of the line that passes through the points given in the table and the y-intercept of the line. The slope of a line can be calculated using the formula $m=\frac{y2-y1}{x2-x1}$, where $(x1,y1)$ and $(x2,y2)$ are any two points on the line. The y-intercept is the y-coordinate of the point where the line crosses the y-axis, which is when x = 0.

Step 2 ：We can use the points (-3, 5) and (-2, 2) to calculate the slope, and the point (0, -4) gives us the y-intercept directly.

Step 3 ：Calculating the slope: $m=\frac{2-5}{-2-(-3)}=-3.0$

Step 4 ：The y-intercept is the y-coordinate when x = 0, so the y-intercept is -4.

Step 5 ：Final Answer: The slope of the line is $\boxed{{\displaystyle -3.0}}$ and the y-intercept is $\boxed{{\displaystyle -4}}$.
