Answer:
.
Step-by-step explanation:
From the given graph it is clear that the y-intercept is 16.
The line passes through (-2,24) and (2,8). So, slope of line is
Slope intercept form of a line is
where, m is slope and b is y-intercept.
Substitute m=-4 and b=16 in the above equation.
Therefore, the required equation is
.
Hi!
You need to multiply to remove the variable from the denominator.
The answer is m=-9
Answer:
Step-by-step explanation:
The figures are similar.
<u>Corresponding sides have same ratio:</u>
1)
- 18/24 = (x - 6)/39
- x - 6 = 39*3/4
- x - 6 = 29.25
- x = 35.25
2)
- 18/24 = y/27
- y = 27*3/4
- y = 20.25
