Final answer:
The slope of the line y=-0.25x + 3 is -0.25. The slope of the line perpendicular to it is 4.
Step-by-step explanation:
The line given in the question is y = -0.25x + 3. We can determine the slope of this line by comparing it to the standard form of a linear equation: y = mx + b. The slope of the line is represented by the m term, so in this case, the slope is -0.25.
Now, to find the slope of a line perpendicular to this line, we can use the fact that the product of the slopes of two perpendicular lines is always -1. So, the slope of the line perpendicular to y = -0.25x + 3 would be the negative reciprocal of -0.25.
Since the negative reciprocal of -0.25 is 4, the slope of the line perpendicular to y = -0.25x + 3 is 4.
