Question

Graph of y=ax+b intersects X-axis at _(dash) point​

Answer 1

Question:

Fill in the blank:

Graph of y = ax + b intersect x-axis at

.

Answer:

(-b/a , 0)

Explanation:

We know that,

At x-axis, the y-coordinate is equal to zero.

Thus,

The point of intersection of the given line with the x-axis will be in the form of (x,0).

Also,

The coordinates of the point of intersection will satisfy the equation of the given line.

Thus;

Putting y=0 in the equation of the given line,

We get;

=> y = ax + b

=> 0 = ax + b

=> ax = - b

=> x = - b/a

Thus,

The point of intersection of the given line with the x-axis is (-b/a , 0).

Hence;

Graph of y = ax + b intersect x-axis at

(-b/a , 0) .

Answer 2

Step-by-step explanation:

y=ax- b (ab/a,O)

y=ax-b

O=ax-b

ax-=+b

X=-b/a
