First you need to know that slope-intercept form is written as y=mx+b

b= y-intercept and m= slope

I'll first start with line number one.

First, you can see that line number one crossed the y-intercept at 2.

So far we have y=mx+2

Next to find slope either do Y2-Y1/X2-X1 or M = Rise/Run

I'll do rise/run. I picked two points. (I provided a picture) An I went up 1 and went to the right 2. Giving you a slope of 1/2. If I add this to my my slope-intercept form I would get y=mx+b. Which is D.

Just do that for the rest of them.      

But, here is the Code: DGBH

Let me know if anything is incorrect!

The points (4,k) and (5,-8) fall on a line with a slope of -7. what is the value of k?
babunello [35]

Answer:

k= -1

Step-by-step explanation:

To find k, use the points and the m =-7 in the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}\\\\-7=\frac{-8-k}{5-4} \\\\-7 = \frac{-8-k}{1}\\\\-7=-8-k\\\\k = -8+7\\\\k=-1

I need help with this! Quick ASAP?
sp2606 [1]

Answer:

a) F

b) B, E, D

Step-by-step explanation:

a) The segment with the greatest gradient has the largest change in y-values per unit change in x-values

From the given option, the rate of change of the <em>y </em>to the<em> </em>x-values of B = the gradient = (4 units)/(2 units) = 2

The gradient of F = (-3units)/(1 unit) = -3

The gradient of A = 4/4 = 1

The gradient of C = -2/5

The gradient of D = 2/6 = 1/3

The gradient of E = 3/4

The segment with the greatest gradient is F

b) The steepest segment has the higher gradient

From their calculated we have;

The gradient of segment B = 2 therefore, B is steeper than E that has a gradient of 3/4, and E is steeper than D, as the gradient of D = 1/3

Therefore, we have;

B, E, D.
