To write the equation of a line in point-slope form, we use the formula:
y – y1 = m(x – x1)
Here, (x1, y1) is a point on the line, and m is the slope. In your case, the point provided is (4, 4), meaning x1 = 4 and y1 = 4. The slope m is given as 4.
Substituting these values into the point-slope formula gives us:
y – 4 = 4(x – 4)
Now, we can simplify this further if needed:
y – 4 = 4x – 16
Then, by adding 4 to both sides:
y = 4x – 12
So, the equation of the line in point-slope form is:
y – 4 = 4(x – 4)
And in slope-intercept form, it can be expressed as:
y = 4x – 12
This equation represents the line that passes through the point (4, 4) with a slope of 4.
