Question

I don't understand what I am supposed to do I think I am supposed to turn this into slope intercept form but, I don't know how. Will someone please help me? What is the equation that represents a line passing through the point 2, -4 with a slope of 1/2?

Answer 1

slope-intercept form:
y=mx + b
where m = slope, and b = y-intercept

Answer 2

They already give you the slope, so what's the first step?

Answer 3

I am not sure sorry I'm terrible at slope intercept form. :(

Answer 4

y = mx + b
slope(m) = 1/2
(2,-4)...x = 2 and y = -4
now we sub...and since we already have slope(m), we need to find y intercept(b)
-4 = 1/2(2) + b
-4 = 1 + b
-4 - 1 = b
-5 = b

so your equation is : y = 1/2x - 5

Answer 5

quote: "slope of 1/2"
If m= slope in the equation y=mx + b, what can you replace "m" with?

Answer 6

1/2?

Answer 7

correct.

Answer 8

if slope is m then what is b? and what is y? What do these represent?

Answer 9

b is the y-intercept. But you should look at @kelliegirl33 's post. She told you step by step what to do, and gave you the answer. :)

Answer 10

ok I am just trying to do the same thing she did on paper so that I can understand how to do this I am still confused a bit not much though thanks

Answer 11

I think I got it now thank you both! :) I am just a little confused at the end of this problem but, I will keep practicing thank you!

Answer 12

good luck...with enough practice, you will soon be helping others learn this
