Given the points:
(2, 7)
x1= 2
y1 = 7
Write the equation of the line
The equation of the line can be written in point-slope form.
Point-slope form:
y - y1 =m(x -x1)
Solution:
Before we can write in point-slope form, we must first find the slope of the line, we can find the slope by using the slope formula.
m = y1/x1
m = 7/2
Substitute the given values of x1, m and y1 to the formula for the point-slope form.
y - 7= 7/2 ( x -2)
Final answer:
y - 7= 7/2 ( x -2)
