What is the first step in solving 3x+2y=10 for y?

Type response here

What is the first step in solving 3x+2y=10 for y?

subtract 3x from both sides: +2y=10-3x

Multiple Choice

Which of the following equations is equivalent to $9x-7y=-7$

$y=-\frac{9}{7}x-7$

$y=\frac{9}{7}x+1$

$y=\frac{7}{9}x+1$

$y=-\frac{9}{7}x+1$

Multiple Choice

What is the equation $3x-2y=-16$ solved for y?

$y=-\frac{3}{2}x+8$

$y=\frac{3}{2}x-8$

$y=\frac{3}{2}x+8$

$y=-\frac{3}{2}x-8$

Multiple Choice

3x + y = 12

y = -3x +12

x = y + 4

x = y + 12

y = 3x -12

Why do we need to solve for y?

So we can graph in desmos
You can only graph things that start with y=

Multiple Choice
