How many solutions does the system have? y=-5x-1 y=-5x+7

Step-by-step explanation:

to do these types of problems, we must compare the slopes and the y int's

in y = mx + b form, the slope will be in the m position and the y int will be in the b position.

y = mx + b

y = -5x - 1slope here is -5 and y int is -1

y = -5x + 7slope here is -5 and y int is 7

learn theseit really helps

if the slopes are the same, but the y int different, there is no solution because ur lines are parallel

if the slopes are different and the y int are different, then there will be one solution

if the slopes are the same and the y int are the same, there is infinite solutions because u have the same line.

so the answer to this problem is : NO SOLUTIONS...ur lines are parallel and never cross

step-by-step explanation:

just keep timing it by 4.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
