Question 669074
Using the slope of {{{7/3}}} and the (7, 9) coordinates
...
y = mx+b
...
9 = {{{(7/3)7 + b}}}
b = 9 - {{{49/3}}}
{{{b = 27/3 - 49/3 = -22/3}}}
...
Solve for x
2 = {{{(7/3)x - 22/3}}}
Multiply the entire equation by 3
6 = 7x - 22
...
Isolate x
7x = 6 + 22
7x = 28
Divide both sides by 7
{{{highlight_green(x = 4)}}}
