Question

Write the equation of the line, in slope-intercept form y=mx+b, that has a slope of 9 and a y-intercept of -3.

Answer 1

Explanation:

We are supposed to write the equation in slope intercept form of a line . Firstly we know the slope intercept form as ,

`\implies\sf y = mx + c`

Where ,

• m is the slope
• c is the y Intercept .

Now by question , the given data is ,

• m = 9
• c = -3

On substituting the respective values we have ,

`\sf\implies y = 3 * x + (-3)\\\\\sf\implies\red{ y = 3x - 3 }`

Hence the slope intercept form is y = 3x - 3 .
