Linear Equations - Graph the following: y = (7/3)x - 4. I did the math and got the following line coordinates starting from (0, -4): (1, -(5/3)), (2, 2/3), (3, 3), (4, 16/3), (5, 23/3). I'm not sure if I understood the slop-intercept equation.

$\large\color{royalblue}{  y =\left(\begin{matrix} \frac{\LARGE  7}{\LARGE 3}\ \end{matrix}\right) x- 4             }$

x=0,     y=-4                                        correct.
x=1,     y=(7/3)-4     >>     y=-5/3       correct.
x=2      y=(14/3)-4    >>    y=2/3         correct.
x=3      y=(21/3)-4    >>    y=3           correct.

solomonzelman · Answer

and on adding 7/3 to the y every time, as you add 1 to the x.

solomonzelman · Answer

yes, every point is correct.
well done.

@SolomonZelman  But the graphing calculator doesn't seem to agree with it....
