Slope intercept form of slope 5 and (2,3)<br><br> explain please!
Bingel [31]

Answer:

<h2>y = 5x - 7</h2>

Step-by-step 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            <em>subtract 10 from both sides</em>

-7=b\to b=-7

Finally:

y=5x-7
