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)
The Slope is 4.
3) Find the y-intercept
So, we can place a given point and slope into a y=mx+b function.
Next, we can substitute the point and slope.
4) Finally, place it all in slope intercept form
y = 4x-1
Answer:
Slope is - 2 because The slope-intercept form is y=mx+b where m is the slope value. In the equation y=-2x , the m value is - 2 .
