____ [38]

Answer:

x=-2

Step-by-step explanation:

Given: Equation is -4(x-3)=20

To find: flaw in Gwendolyn's work and the correct solution to the equation.

Solution:

In the given question,

the first step is -4(x-3)=20

The second step is -4x+12=20

(This step is obtained on multiplying -4 by x-3)

The third step is -4x=32

This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:

-4x=20-12\\-4x=8\\x=-2

So, the correct solution is x=-2

What is the slope-intercept equation for this line?
Vaselesa [24]

Answer:

y=-\frac{1}{4} x-1

Step-by-step explanation:

find the slope of the line using the two points (0,-1) and (4,-2)

\frac{(-2+1)}{(4-0)} =-\frac{1}{4}

since we already know that the y-intercept is -1 then you plug the numbers into the slope-intercept form y=mx+b and you get y=-\frac{1}{4}x-1
