Slope intercept form.Please help

Mathematics
1 answer:
denis23 [38]3 years ago
6 0

Answer:

y2-y1/x2-x1 = 3-3/4-(-6) = 0/10

y = mx+b = 3 = 0(4) + B = B = 3

y = mx+b = y = 0x + 3

Step-by-step explanation:

If you know two points on a line, you can use them to write the equation of the line in slope-intercept form. The first step will be to use the points to find the slope of the line. This will give you the value of m that you can plug into y = mx + b. The second step will be to find the y-intercept.

What is the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 ​
andreyandreev [35.5K]

<u>Answer:</u>

The equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 ​is y+6=\frac{1}{3}(x+2)

<u>Solution:</u>

Given that line passes through (-2, -6) and has slope of 1/3

We have to find the equation of the line

The point slope form is given as

y-b=m(x-a)

where m is the slope of the line and a, b are the x, y coordinates of the given point through which the line passes.

Here in this question, m = 1/3 and a = -2 and b = -6

By substituting in point slope form we get,

y - (-6) = \frac{1}{3}(x - (-2))\\\\y + 6 = \frac{1}{3}(x + 2)

Hence the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 ​is y+6=\frac{1}{3}(x+2)

1/4(x+3)+3/8x=13/4 SOLVE FOR X
larisa86 [58]
1. First I turned the fractions into decimals, just to make things easier for me.2. That gave me => (.25x)+(.75)+(.375)=(3.25)
3. Then, I combined like terms and move my equation around; so, that gave me (.25x) = (3.25) - (.75) - (.375) and when I solve the right side of the equation it gives me
(.25x) = (2.125)
4. After combining like terms and simplifying (the way I did in step 3), I will divide both sides by .25, to get the value of X alone; so, my equation then looks like => x=8.5

Step-by-step explanation:

There are 16 ounces per 1 pound.

4 ounces per shell.

16 x 12 = 192 ounces

192 ounces divided by 4 = 48
