Answer: -4
Step-by-step explanation:
To find the slope of the graph represented by the equation 8x + 2y = 13, we need to rearrange the equation into slope-intercept form, which is y = mx + b.
Let's solve for y:
8x + 2y = 13
2y = -8x + 13
y = -4x + 6.5
Now we can see that the coefficient of x, which is -4, represents the slope of the graph.
Therefore, the slope of the graph is -4.

Step-by-step explanation:
watching a television with a 13-inch screen to a television
with a similar 19-inch screen. If a boxcar
appeared 8 inches long on the 13-inch screen, how
long, to the nearest inch, will it appear on the 19-inch
screen?
The boxcar will appear 12 inches long on the 19-inch screen.
To find out how long the boxcar will appear on the 19-inch screen, we can set up a proportion using the relationship between the screen sizes and the length of the boxcar. Let's call the length of the boxcar on the 19-inch screen 'x'. So, we have the proportion:
13/8 = 19/x
Solving for 'x', we can cross multiply and divide:
x = (19 * 8)/13
Calculating this gives us 'x' to be approximately 11.7 inches. Rounding to the nearest inch, the boxcar will appear 12 inches long on the 19-inch screen.
