Answers:
- y intercept = 3/5
- x intercept = -1
- slope = 3/5
=========================================================
Explanation:
The two points (-1,0) and (4,3) are on the line.
Let's use the slope formula
m = (y2-y1)/(x2-x1)
m = (3-0)/(4-(-1))
m = (3-0)/(4+1)
m = 3/5 is the slope
-------------------
The x intercept is -1 because this is where the line crosses the x axis.
The y intercept is a bit more tricky. It appears the graph is crossing at y = 0.5 on the y axis, but this may not be the case.
Let's find out
y = mx+b
0 = (3/5)*(-1)+b
0 = -0.6+b
0.6 = b
b = 0.6
b = 3/5 is the y intercept
Coincidentally, the slope and y intercept are the same value. This won't always happen.
