MArishka [77]

Solution, -13+\left(-21\right)-\left(-18\right)+10-\left(-23\right)=17

Steps:

-13+\left(-21\right)-\left(-18\right)+10-\left(-23\right)

\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations},\\\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:

\mathrm{Apply\:rule\:}+\left(-a\right)\:=\:-a,\\+\left(-21\right)=-21,\\-13-21-\left(-18\right)+10-\left(-23\right)

-13-21=-34,\\-34-\left(-18\right)+10-\left(-23\right)

\mathrm{Apply\:rule\:}-\left(-a\right)\:=\:+a,\\-\left(-18\right)=+18,\\-34+18+10-\left(-23\right)

-34+18=-16,\\-16+10-\left(-23\right)

-16+10=-6,\\-6-\left(-23\right)

\mathrm{Apply\:rule\:}-\left(-a\right)\:=\:+a,\\-\left(-23\right)=+23,\\-6+23

Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4). Include your work in
maw [93]
Firstly, we need to understand the formula of point-slope form:
y1 - y2 =m( x1 - x2)

Where x and y is the coordinates and m is the slope respectively.

To find the slope:
\frac{y1 - y2}{x1 - x2}
In this case:
\frac{5 - 4}{ - 3 - ( - 1)}  \\  =  \frac{1}{ - 3 + 1}  \\  =  -  \frac{1}{2}

We can then put the above slope and the point (-1,4) into the formula:

4-y = -1/2(-1-x)
-y = 1/2+1/2x-4
y = -1/2x+7/2

Alternatively:

y-4=-1/2(x-(-1))
y=-1/2x-1/2+4
y = -1/2x+7/2

Therefore the answer is y = -1/2x+7/2.

Hope it helps!
