Antoinete needs to sove this system of equations by graphing. Which statements explain how she should graph the equations? Check all that apply.
2x-y-58
y-25x+4
D She should rewrite both equations in slope-intercept form.
O She should rewrite the first equation in slope-intercept fom.
O She should find that the second equation has a slope of 4
OWhen rewriting the first equation, she shoud subtract 2x from each side of the equation to get -y by itselt.
DAfter rewriting the first equation in slope-intercept form, she shouild find that both ines have negative slopes.

- "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."

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
