Brut [27]

Answer: y = 4x-1

Step-by-step explanation:

1) Choose two points for the later equation.

For this example, I will use (-1,-5) and (2,7)

2) Place it in a rise/run equation. (y/x)

\frac{y2-y1}{x2-x1} \\\\\frac{7-(-5)}{2-(-1)} \\\\\frac{12}{3} \\\\4

The Slope is 4.

3) Find the y-intercept

So, we can place a given point and slope into a y=mx+b function.

y=4x+b

Next, we can substitute the point and slope.

7 = 4(2)+b\\7=8+b\\-1=b

4) Finally, place it all in slope intercept form

y = 4x-1
