Answer:
y = 0.8x + 0.5
Step-by-step explanation:
First, find the slope using two pairs of values, (0.5, 0.9) and (0.75, 1.1):
![slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1.1 - 0.9}{0.75 - 0.5} = \frac{0.2}{0.25} = 0.8](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%3D%20%5Cfrac%7B1.1%20-%200.9%7D%7B0.75%20-%200.5%7D%20%3D%20%5Cfrac%7B0.2%7D%7B0.25%7D%20%3D%200.8%20)
m = 0.8
Find y-intercept, b, by substituting x = 0.5, y = 0.9 and m = 0.8 into y = mx + b
Thus:
0.9 = (0.8)(0.5) + b
0.9 = 0.4 + b
0.9 - 0.4 = b
b = 0.5
To write the equation substitute m = 0.8, and b = 0.5 into y = mx + b.
Thus:
y = 0.8x + 0.5
Answer:
t = 8/9
Step-by-step explanation:
There are many possible solutions that could be expressed as equivalent to the equation 10t - 4t + 3t = 8. With that being said, here is a simplified form, solved for t.
10t - 4t + 3t = 8
6t + 3t = 8
9t = 8
t = 8/9
Each of these form's is an equivalent equation to the one written by Mrs. McAlister.
If you can provide the table of student answers, we could answer which students were correct or wrong. Without the table, we can only guess.
