Answer:
-2.5
Step-by-step explanation:
We need to find the slope using and two points
m = ( y2 -y2)/(x2-x1)
= ( 25-20)/(-10 - -8)
= 5/( -10+8)
= 5/-2
- 2.5
Answer:
y = 2x + 4
Step-by-step explanation:
The question is asking for the equation of the line in slope-intercept form: , where m is the slope and b is the y-intercept.
The y-intercept is where the graph of the line crosses the y=axis, which in this case is at y=4 -- which means that b=4.
We can see that (-2, 0) and (0, 4) are two points on the line. The equation for the slope is , which is (4-0)/(0-(-2)). This is equal to 2. (note: you can think of the slope as rise/run)
Therefore, the equation for the line is y = 2x + 4.
