## Barrelracing one year ago Write the equation of the line that passes through (1, 5) and (–2, 14) in slope-intercept form. a) y=3x + 2 b) y= 3x + 8 c) y = -3x - 2 d) y = -3x + 8

I just need the formula. I cant find it anywhere.

2. Teddyiswatshecallsme

Do you know how to calculate the rate of change?

Use $$y - y_1 = m(x - x_1)$$ and then turn it into point slope form

4. marihelenh

$\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$ will give you the slope, and then use the formula @Nixy gave you.

You can get the slope with $$\huge m = \frac{y_2-y_1}{x_2 - x_1}$$

6. Barrelracing

y = -3x + 8

You are correct @Barrelracing
