Question 1072727
consider the linear equation 2x-3y=-3. if (-3,y1) is a point on the graph of the line, find the missing coordinate. y1=? And if (x2,1) is a point on the graph of the line, find the missing coordinate. x2=?
<pre>2x - 3y = - 3
Substitute - 3 for x and find y, which is the same as: {{{y[1]}}}
{{{highlight_green(matrix(1,5, y, or, y[1], "=", - 1))}}}
Apply the same concept for the 2nd part, and you should be able to find x, which is the same as: {{{x[2]}}}.</pre>
