write an equation of the line with slope = 7/8 and containing the point (6,3)
:
Use the point/slope formula: y - y1 = m(x-x1)
m = 7/8; x1 = 6, y1 = 3
:
y - 3 = 7%2F8%29(x - 6)
:
y - 3 = 7%2F8%29x - 6*7%2F8
:
y - 3 = 7%2F8%29x - 42%2F8
:
y - 3 = 7%2F8%29x - 21%2F4
Add 3 to each side
y = 7%2F8%29x - 21%2F4 + 3
:
y = 7%2F8%29x - 21%2F4 + 12%2F4
:
y = 7%2F8%29x - 9%2F4; is the equation
:
:
Check this, replace x with 6, find y
y = 7%2F8%296 - 9%2F4
y = 42%2F8%29x - 9%2F4
y = 21%2F4%29 - 9%2F4
y = 12%2F4 = 3, confirms our equation
