Pls answer a and b I will give brainliest answer
Natali5045456 [20]

Answer:

a. True, b. y = (-1/2)x + 8

Step-by-step explanation:

Because the graph is a straight line, that means that the graph is in fact proportional. For the equation, take the form y = mx+b. Plug in the slope, which is -1/2, and the y-intercept, which is 8, which would give you the equation y = (-1/2)x + 8.

‼️ IM BEING TIMED PLEASE HELP‼️<br><br> Which is the graph of fix) = 4(3)?
dexar [7]

Answer:

Step-by-step explanation:

After graphing the function f(x) = 4(\frac{1}{2})^{x}  we can see that the correct graph is the middle one in the picture. This is because with an x-input of 1 the value of 1/2 will stay the same and when multiplied by 4 it would give us a y-coordinate of 2 as seen in the middle graph. The y-coordinate keeps decreasing exponentially by half for every increase in the x-coordinate. A zoomed-in version of the graph can be seen in the attached picture below for a better understanding.
