Which equation represents the line 3x - 2y = -8 in slope-intercept form?
1 answer:
Answer:
The slope -intercept form of the equation is;
y = x + 4
Step-by-step explanation:
The slope-intercept form of an equation is;
y = mx + c
where m is the slope and c represent the intercept
To represent the equation given; 3x - 2y = -8 in its slope intercept form, we will follow the steps below:
3x - 2y = -8
subtract 3x from both-side of the equation
3x - 3x -2y = -3x - 8
-2y = -3x -8
Divide throught the equation by -2
-2y/-2 =-3x/-2 -8/-2
y = x + 4
The slope -intercept form of the equation is;
y = x + 4

Answer: 26.8 feet
Step-by-step explanation:
In the figure attached you can see two right triangles triangle ABD and a triangle ACD.
You are located at point B and the other person at point C.
The approximate height of the lifeguard station is <em>x</em>.
Keep on mind that:
Therefore:
<em>For the triangle ABD</em>:
[EQUATION 1]
<em>For the triangle ACD:</em>
[EQUATION 2]
Solve from DC from [EQUATION 2]:
Substitute into [EQUATION 1] and solve for x:
≈26.8ft
