Answer:

y+3=13(x-8)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(10-(-3))/(9-8)

m=(10+3)/1

m=13/1

m=13

y-(-3)=13(x-8)

y+3=13(x-8)

What is the slope of the graph?
Alexus [3.1K]

I see lattice points (0,-3) and (4,4) so slope is change in y over change in x,

m = (4--3)/(4-0) = 7/4.

The y intercept is when x=0, so (0,-3), often just called -3.

So the equation is

y = (7/4) x - 3

Answer: Slope 7/4, y intercept -3

Please help me!! I already did most of the question
MArishka [77]
Slope is (47 - 15) / (7 - 1) = 16/3

we have equation in the form y = mx + b so m = 16/3 so
y = 16/3 x + b

we know that (1,15) is on this line.
(1,15) on the line means when x = 1, y = 15 so plug and chugg

15 = (16/3)*1 + b
15 - 16/3 = b
45/3 - 16/3 =  b
b = 29/3

so your equation looks like

y = (16)/(3)x + (29)/(3)

Mandy, Carly, and Armond collect sports jerseys. Carly has 5 more jerseys than Mandy, and
IgorLugansk [536]

Answer:

Carly has 17 jerseys

Step-by-step explanation:

Here, we want to know the number of jerseys Carly has

Let the number of jersey Carly has be c

Armond has 3 times what Carly has. The number of jerseys Armond has will be 3 * c = 3c

Carly has 5 more jerseys than Mandy; this means that the number of jerseys Mandy has is c-5 jerseys

Adding all, we have 80 jerseys

Thus;

c + 3c + c-5 = 80

5c -5 = 80

5c = 80 + 5

5c = 85

c = 85/5

c = 17
