Interpret Slope and Y-Intercept on Graphs

The first equation in a system of two equations is x + 4y = 8. If the graph of the second equation does not intersect the graph of the first equation, what could be a second equation for this system?

(HINT: Convert the first equation to slope-intercept form.)

• y = 4x + 1

• y = 1/4x - 2

• y = -4x + 3

• y = -1/4x - 5

• When there are zero visitors, we predict negative 75 degrees that day on the beach.  

• When the temperate is zero, we predict negative 75 visitors on the beach.  

• When the temperate is zero, there will be negative 75 visitors on the beach.  

• There is no y-intercept
