Question

Complete the equations of the system in slope-intercept form. Use a decimal for the slope if necessary.


Line 1
x y
0 3
1 5

Line 2
x y
–1 1
–2 –1



Line 1: y = x +

Line 2: y = x + @perl .......i have no idea

Answer 1

@perl i have no ideo

Answer 2

First start with the slope formula of m=(y2-y1)/(x2-x1)

Answer 3

And then for line 1 you already know the y intercept so y=mx+b should be easier to figure out

Answer 4

i havt a hard time with this

Answer 5

Ok for slope formula. y2-y1=5-3 and the. You divide that by x2-x1 which equals 1-0. So the slope for line 1 is m=2/1=2.

Answer 6

line 1 slope: $$\Large {m=\frac{5-3}{1-0}} $$

Answer 7

m=2/1?

Answer 8

Once you find out the slope like perl gave a good illustration for, look at the ordered pairs. Do you have an x that is 0? Well we know that for lines the y intercept is (0,y)

Answer 9

the y intercept is the point (0,b)

Answer 10

thats given in the directions

Answer 11

m = 2
y intercept b is 3

y = mx + b

now put it together

Answer 12

can u give me the answer i'm completely lost now
