Question

There is a line that includes point (1,2) and has a slope of 10 what is equation in intercept form

Answer 1

`y=10x-8`

Explanation:

Given: Point (1,2) lies on the line such that it's slope is 10.

To find: equation of line

Solution:

Let m be the slope of line and b be the y - intercept.

Here, slope is a number that describes the direction and the steepness of the line.

y-intercept is the y-coordinate of the point where the graph of the line intersects the y-axis.

Equation of line is
`y=mx+b`

Put
`(x,y)=(1,2),m=10`

`2=10(1)+b\\2=10+b\\b=2-10=-8`

So, equation of line is
`y=10x-8`
