Answer: y = 1x -3
The 1 is not necessary so
y= x - 3
Step-by-step explanation:
(y- y1) = m(x -x1). First
Substitute y and x-values from the given coordinates and solve for x.
7-(-1)=m(10-2)
8 = m(8) 8/8=1 T
m= 1 The slope, m is 1
Then substitute values of y and x from either given coordinate into the equation and solve for b, the y-intercept.
y=mx+b
-1= 1(2)+b
-1=2+b subtract 2 from both sides.
-1-2 = b
-3 = b
OR
7= 10 + b
-10 +7 = b
-3 = b
Finally, write the equation with the values for m and b
y = 1x +(-3) Simplify & Rewrite
y= x - 3
Find a common denominator to subtract, so smallest common denimator between 7 and 3 is 21
multiply 4/7 by 3/3 and 2/3 by 7/7
12/21-14/21= -2/21
<em> 5 3/8</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>1 1/2 + 3 7/8 =</em>
<em>= (1×2+1)/2 + (3×8+7)/8</em>
<em>= ⁴⁾3/2 + 31/8</em>
<em>= 12/8 + 31/8</em>
<em>= (12 + 31)/8</em>
<em>= 43/8</em>
<em>= 5 3/8</em>
<em>Good luck !</em>
