Question

Write the equation of the line when the slope is 3 and the line goes through the point (3,2).

Answer 1

y = 3x -7

Explanation:

Since we already know that the slope is 3 and it goes through the point (3,2).

We can use - Slope intercept form: y = mx + b to find the y-intercept first.

Using the given info:

m = 3

x = 3

y = 2

Thus,

2 = 3(3) + b

2 = 9 + b

2- 9 = 9- 9 + b

-7 = b

Hence, the y-intercept is -7.

As a result,

y = mx + b >> plug it in

y = 3x -7
