What is the equation of a line passing through the point (a, b) and having a slope of b?

Answers

From the slope form of a line;
(y-b)/(x-a) =b
y-b=bx-ab
y=bx-ab+b
y=bx-b(a-1)

Answer:

The equation is y-a= b(x-b)

Step-by-step explanation:

I use bold for the slope so you can differentiate the slope term b from the y coordinate value b.

The equation of a line passing through a specific point and having a specific slope can be obtained using the point slope form of a line :

y-y1=m(x-x1) where m is the slope and (x1,y1) is your specific point.

So replacing your values, the point  (x1,y1) =(a,b) and m=b, in this equation we havE:

y-a= b(x-b)

That can be expressed in point slope form and explicit for as.

y = b(x-b) + a = bx -bb +a =

y= bx + (a -bb)

Simplify expressions
2=3/4x-7

Answers

Answer: x = 12

Step-by-step explanation:

2=(3)/(4)x-7

Add 7 on both sides to get rid of the 7 and isolate x.

+7+2=(3)/(4)x-7+7

9=(3)/(4)x

Now multiply both sides by (4)/(3) to eliminate it and isolate x.

((4)/(3))(9)=((3)/(4)x) ((4)/(3))

12=x

Proof;

2=(3)/(4)x-7\n2=(3)/(4)(12)-7\n2=9-7\n2=2

Answer:

x = 12

Step-by-step explanation:

2 = 3/4x - 7

2 + 7 = 3/4x

9 = 3/4x

9 × 4x = 3

36x = 3

x = 36/3

x = 12
