Write an equation in slope-intercept form that passes through each pair of points. (0, 1) (-3, 1)
lina2011 [118]

Answer:

y =  \frac{0}{ - 3}  + b

Step-by-step explanation:

Slope intercept formula is y=mx+b

(m) is slope

(b) is the y intercept

We'll find slope first.

slope formula is

\frac{y2 - y1}{x2 - x1}

y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.

So we just put the given values into our equation.

\frac{1 - 1}{ - 3 - 0}

Simplify

\frac{0}{ - 3}

Now we put this into our y=mx+b

y=0/-3x+b

now we need the (b)

to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.

y =  \frac{0}{ - 3} x + b

1 =  \frac{0}{ - 3} (0) + b

Solve

1=0+b

b=1

Put this in our formula

y =  \frac{0}{ - 3}  + 1

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Emma,Brandy, and Damian will cut a rope that is 29.8 feet long into 4 jump ropes . Each of the 4 jump ropes will be the same len
mixas84 [53]
Hi! To caculate this problem you want to do 29.8 divided by 4. Since there is a 29.8 foot rope and they are wanting to cut it into 4, you need to divide. It will end up dividing into a decimal but will not repeat!

Hope this works! If not please comment what else you are looking for!

A line goes through the points (8,9) and (2,4).
Nadusha1986 [10]
9-4/8-2
5/6
The slope is 5/6
y-4=5/6(x-2)
y-4=5/6x-5/3
y=5/6x+7/3
The equation of line in point-slope is y - 4 = 5/6(x - 2)
The equation of the line in slope-intercept is y = 5/6x + 7/3
