Question

Slope intercept form of slope 5 and (2,3)

explain please!

Answer 1

y = 5x - 7

Explanation:

The slope-intercept form:

`y=mx+b`

m - slope

b - y-intercept

We have the slope m = 5. Therefore we have the equation

`y=5x+b`

Put the coordinates of a given point (2, 3) to the equation:

x = 2, y = 3

`3=5(2)+b`

`3=10+b` subtract 10 from both sides

`-7=b\to b=-7`

Finally:

`y=5x-7`
