Write the slope-intercept form equation of the line that passes through (1,-1) and (2, 2).

mixer [17]

Answer:

The answer to your question is y= 3x - 4.

Step-by-step explanation:

Plot the points (1,-1) and (2,2) and get your slope, in the case of slope-intercept form "m" using the rise/run method. You rise 3 units and run one unit to the right to get from (1,-1) to (2,2), so your slope is 3/1 or just simply 3. -4 is your y-intercept, or "b", because if you plot the two aforementioned points (1,-1) and (2,2) and make a line with them, your line meets the y-axis at the point (0, -4). Hope this helps!

The ratio of the number of A's in the class to B's in the class was 2:5. How many people got A's if there were 40 people who got

Umnica [9.8K]

Answer:

16 students got an A

Step-by-step explanation:

Set up an equation to compare the ratio to the scores:

$\frac{2}{5} = \frac{x}{40}$

Cross multiply:

80 = 5x

Divide each side by 5:

x = 16

Now, check if $\frac{16}{40} = \frac{2}{5}$

16/8 = 2

40/8 = 5

The ratios are the same! Therefore, 16 students got an A!

Hope this helps! Feel free to contact me if you have any questions :)

Dovator [93]

♥ To solve find how much this will cost AFTER the price increases.
♥ Solve:
Multiply the original price as it is by: <span>1.057 (5.7 as a decimal would be 0.057, but as i said to keep the original price, the 1 will keep it there.)
</span> $185 * 1.057 = $195.545$
Final answer: <span>$195.54</span>
