Im guessing that this is a distance over time graph. if so, the gradient of the line of best fit would have a low value. (not be very steep)
The angle of the graphed slope changes with changes in speed.

No. The slope on a speed vs time graph tells the acceleration.
The slope of the speed-vs-time graph is the magnitude of acceleration.
A graph requires two numerical variables before it can have a meaningful slope. A distance-graph has only one variable so it does ot have a slope in any meaningful way. For eaxmple, you could have a graph showing the distances of varoius places from, say London.
If it is distance from a point versus time, with distance on the vertical axis and time on the horizontal axis, it would show a steep vertical climb on the graph. The steeper vertical change, the faster, but never completely vertical. Large "rise" (distance) over short "run" (time). With 0 acceleration, the graph is a straight line.
acceleration
Acceleration is how fast you get up to speed.
If the slope is 'uphill' then the car is going faster
The slope of a speed/time graph at any point is the acceleration at that instant.
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
The slope of a velocity-time graph represents acceleration.
