Answer:
Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, <em>or</em><em> </em>insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
<em><u>Point-slope form:</u></em>
Where:
is the slope
and 
are corresponding coordinate points 
Insert the given values:
Solve for y. Expand the right sie using the distributive property:
Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:
<em>OR</em>
<em></em>
<em><u>Slope-intercept form:</u></em>
Where:
- is the slope
is the y-intercept
and 
are corresponding coordinate points
Insert the given values:
Simplify the multiplication:
Solve for b. Add 10 to both sides, canceling out the 10 on the right:
The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:

Answer:
y = -2x -3
Step-by-step explanation:
- the altitude trough F is a perpendicular line to the line DE
- find slope of line DE
D ( x2 = -5, y2 = -1); E (x1 = 3, y1 = 3)
slope m = (y2-y1) / (x2-x1) = (-1-3) / (-5-3) = -4/ -8 = 1/2
-find equation of the altitude trough F
lines that are perpendicular have the slope negative reciprocal (negative reciprocal of 1/2 is -2)
y= -2x +b , for point F(1, -5)
-5 = -2*1 +b, add 2 to both sides
-5 +2 = b, combine like terms
-3 =b
equation of the altitude trough F is y = -2x -3
Answer:
162
Step-by-step explanation:
260/2=130
130+32=162
Answer:
The chances of landing on blue are 1 in 4, or one fourth. The chances of landing on red are 1 in 4, or one fourth. This problem asked us to find some probabilities involving a spinner.
