Algebra II problem-

[Growler]

Math... really not my strong suit.

This is more like Algebra I, but my class is Algebra II, so whatever.
Directions: Write an equation in slope-intercept form for the line that satisfies each set of conditions.

Problem: slope 3/2, passes through (-5,1)

wtf do I do. So far I have...

y = 3/2 (-5) + b

1 = -15/2 + b

is that the answer?

Having the ESF Forum do your math homework? Oh well, I'm bored...

They want an equation in slope-intercept form, a common form for 2D graphing. It's y = mx + b, where m is the slope, and b is the y-intercept. By pluging the point they give you into the equation, you solve for the intercept that shifts the line to include that point. You half-solved for b. Just find it, and write an equation that uses it and the slope given.

b = 1+ 15/2 = 17/2

Therefore, the equation will go y=3/2*x + 17/2 <-- this is slope-intercept form. Dont comfuse it with standard form, which is Ax + By + C = 0, or something like that.

Maybe you want to do my homework for me... more specifically, question 4d. Everyone I know in MATH 100 is freaking out over this assignment.

I feel soo dumb... How do you do it that quick?

 

[Mr. Phonso]

since growler's question is solved anyone mind answering this one for me..

two times one number exceeds five times another number by 10 (form it into an algebraic equation)

 

[Ravendust]

2 x X > 5 x (Y x 10)?

X = 'one number'
Y = 'another number'

 

[DragonDude]

two times one number exceeds five times another number by 10 (form it into an algebraic equation)

2x = 5y + 10
Take a look at it so you understand how/why it works.

I should post my next calculus assignment here. =o

 

[Rayos]

<--- took calc 3...i don't think you want to see my equations

 

[Mr. Phonso]

sorry but whats the equal sign for?

Who's gonna help me do my calculus
