The table shows the temperature (y) at different altitudes (x). This is a linear relationship. Find the y−intercept for this relationship. Altitude (ft), x 0 2,000 4,000 6,000 8,000 10,000 12,000
Temperature (°F), y 59 51 43 35 27 19 11

The y−intercept for this relationship is b = ???
Please help me! Thank you!

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
