Answer:
y = -1/2x + 5/2
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 2x + 3. Its slope is 2. A line perpendicular to this one will have a slope of -1/2.
Plug this value (-1/2) into your standard point-slope equation of y = mx + b.
y = -1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 2). Plug in the x and y values into the x and y of the standard equation.
2 = -1/2(1) + b
To find b, multiply the slope and the input of x (1)
2 = -1/2 + b
Now, add 1/2 to both sides to isolate b.
5/2 = b
Plug this into your standard equation.
y = -1/2x + 5/2
This equation is perpendicular to your given equation (y = 2x + 3) and contains point (1, 2)
Hope this helps!
How to get answer by Mimiwhatsup:
Let's solve for b.
1/t = 1/a + 1/b
Step 1: Multiply both sides by t.
1= at+bt/ab
Step 2: Multiply both sides by ab.
ab=at+bt
Step 3: Add -bt to both sides.
ab+−bt=at+bt+−bt
ab−bt=at
Step 4: Factor out variable b.
b(a−t)=at
Step 5: Divide both sides by a-t.
b(a−t)/a−t = at/a−t
b= at/a−t
