If you want to be eligible for partial credit, please show your work. Solve the following system of equations using any method. y=1/2x+3 y=1/3x-2 Try substituting the equations. if y=1/3x-2, then 1/3x-2 = 1/2x+3 Solve for x, then plug your solution in for y Does x=4 and y=2 No...

You should make two selections from the list below. Which two of the four equations represents parallel lines? 2x - 3y = -10 6x - 9y = 15 3x + 2y = 10 9x + 6y = 30 i think it's the second one Parallel lines have the same slope. Rework your equations to be in the form y=mx...

Choose the equation of a line that is parallel to y = 3x - 2 and passes through the point (-1,-6). y = 3x + 3 y = 3x - 3 y = (-1/3)x + 19/3 y = (-1/3)x - 19/3 *i think it's the last one! The slope must be 3. That is the "m" term in the form y = m x + b So the ...

What is the slope of the line represented by the equation y = 4? 0 4 -4 Undefined *I think it's 0?Is it? It is zero. (4-0.4)/4= (4-0.4)/4=

PLease help me with this: What kind of line is created when you graph the equation x = -5? Vertical line Horizontal line This equation does not graph a line Parallel line *Ithink it is a vertical line!* Yes, you are correct! It is a vertical line!
