What is the equation in slope intercept form of the line that passes through the points (-6,5) and (2,1) enter any fractions lik

Korvikt [17]

The equation of the line in slope-intercept form is given by

$y=mx+b$

step 1

Find out the slope m

we have the points (-6,5) and (2,1)

$m=\frac{1-5}{2+6}=-\frac{4}{8}=-\frac{1}{2}$

step 2

Find out the equation of the line

we have

m=-1/2

point (2,1)

substitute and solve for b

$\begin{gathered} 1=-\frac{1}{2}(2)+b \\ \\ 1=-1+b \\ b=2 \end{gathered}$

therefore

The equation of the line is

$y=-\frac{1}{2}x+2$

Problem N 2

Write the equation of the line in the point-slope form that passes through the point (-2,3) and has a slope of 1/2

The equation of the line in point-slope form is given by

$y-y_1=m(x-x_1)$

we have

m=1/2

point (-2,3)

substitute

$\begin{gathered} y-3=\frac{1}{2}(x-(-2)) \\ \\ therefore \\ The\text{ answer is} \\ y-3=\frac{1}{2}(x+2) \end{gathered}$

Colt1911 [192]

You would need to put 4 in for (n)so, 5(4)+8 then solve. 5 times 4=20 plus 8 is 28. I hope I could help!

The sum of 11.6 and 4.1 by rounding each number to the nearest whole.

Karo-lina-s [1.5K]

11.6 rounded to the nearest whole is 12 and 4.1 rounded to the nearest whole is 4 (rule is if the decimal [or number in general] is 4 or lower, the whole stays the same and if the number is 5 or higher, the whole goes up by one). 12+4=16
