Point-Slope Form *See photo*

Ne4ueva [31]

Answer:

y = 3x - 5

Step-by-step explanation:

We know that the equation 'y = 3x + ?' intersects the point (1, -2). This means that when x = 1, y = -2 in out equation above. To solve this just plug in the x and y values to get '?'.

$y = 3x + ?\\-2 = 3(1) + ?\\-5 = ?$

Now that we know '?' is -5, we write it back into slope intercept form, so our final answer is y = 3x - 5

Ne4ueva [31]

Answer:

450 minutes

Step-by-step explanation:

15 + 0.1x = 60

15 - 15 + 0.1x = 60 - 15

0.1x = 45

$\frac{0.1x}{0.1} = \frac{45}{0.1}$

x = 450

What is the slope of the line with the equation 3x = -y − 5

prisoha [69]

This equation is written in standard form, so we need to change it into slope-intercept form.

3x = -y - 5

3x + y = -y + y - 5

3x + y = -5

3x - 3x + y = -5 - 3x

y = -5 - 3x

y = -3x - 5

The slope is classified as "m" in this type of equation, so, the slope is -3.

Best of Luck!
