Question

Please help! Will do anything.
Write an equation for each line in point-slope form and then convert it to standard form. Show steps.
1. through (2, 3) and (3, 5)

Answer 1

@jim_thompson5910

Answer 2

Whats the slope of this line?

Answer 3

I think I have to figure it out

Answer 4

yes you would use the slope formula

Answer 5

5-3/3-2
2/1
slope=2

Answer 6

y - y1 = m(x-x1)
y - (3) = 2(x - 2)
y-3=2x-4
Im stuck here

Answer 7

y - 3 = 2(x - 2) is the equation in point-slope form

Answer 8

solve for y

y - 3 = 2(x - 2)

y - 3 = 2x - 4

y = 2x - 4+3

y = 2x - 1

the equation is now in slope intercept form

Answer 9

I need standard form, is that standard form?

Answer 10

to get it into standard form, you need it in Ax+By = C form

Answer 11

usually A > 0

Answer 12

y = 2x - 1

y+1 = 2x

1 = 2x - y

2x - y = 1

and it's now in standard form

Answer 13

in the first one you helped me with was it standard or slope that you gave me?

Answer 14

I don't remember

Answer 15

You'll have to post it

Answer 16

I figured it out yes it was. Could you please help me with another? Sorry its just I am completely screwed because I have a horrible teacher and I have to turn in a study guide and I have like 13 questions I need help with. You don't need to help me with them (unless you want to), but I would appreciate it if you could!!

Answer 17

there was 55 questions in total I just need help with these.

Answer 18

I won't help with all 13, but I'll help with a few more.

Answer 19

thank you!!

Answer 20

Draw a scatter plot of each set of data. Decide whether a linear model is reasonable. If so, describe the correlation. Then draw a trend line and write it's equation. Predict the value of y when x is 15.
1. {(3, 5), (4, 7), (5, 9), (7, 10), (8, 10), (9, 11), (10, 13)}
2. x- 0, 3, 6, 9, 12
y- 17.5, 35.4, 50.5, 60.6, 66.3
this is a table ^

Answer 21

what kind of calculator do you have?

Answer 22

it broke

Answer 23

do you have microsoft excel?
