Answer:

a) y = 3x-1

b) y = x+5

Step-by-step explanation:

a) We notice the x-values change by 1, so the change in the y-value is the slope. -4 -(-7) = 3 is the change between the first two y-values.

The y-intercept is shown by the ordered pair (0, -1). So, the slope-intercept equation is ...

y = 3x -1

b) We note that the change in x is 2 units, as is the change in y. Then the slope of the function is m = 2/2 = 1. The y-intercept (b) can be found from ...

b = y -mx

b = 7 -1·2 = 5

Then the slope-intercept equation is ...

y = x + 5

Abigail realizes that she has too much debt. What is a financially irresponsible decision for Abigail?

Elis [28]

B would be the least wise...loans have interest which means that when you get around to paying them back you owe more than you borrowed and you can get yourself into even deeper debt. Hope this helps, and if you are able to do so, please mark Brainliest! Thanks!

In 4 years, sravani will be 3 times as old as Makayla is currently. three years ago, sravani was 4 times as old as Makayla was t

X - Sravani
y - Makayala

$x+4=3y\\
x-3=4(y-3)\\\\
x=3y-4\\
x=4y-12+3\\\\
x=3y-4\\
x=4y-9\\\\
3y-4=4y-9\\
4y-3y=-4+9\\
y=5\\\\
x=3\cdot5-4\\
x=15-4\\
x=11$

Sravani - 11
Makayla - 5

Simplify the expression -(6 - 4p)

Illusion [34]

Hey there!

The answer to your question is $-6+4p$

Given:

$-(6-4p)$

First, we distribute the negative sign to both terms ( $6$ $and$ $-4p$ ) This would make the $6$ negative and the $-4p$ positive, so we have:

$-6$ $and$ $4p$

Add them together and we get:

$-6+4p$

Have a nice day!
