The graph at the right shows Lanna’s total distance in miles for each day she is training for a marathon. Her friend, Sam, has a distance that can be represented by the function y = 4x, where y
is the number of miles ran and x is the number of days.
Which person is running more per day? How much are they running? The graph at the right
shows Lanna’s total distance in miles for each day she is training for a marathon. What is her
distance on day 10?
How many miles will Sam run by day 10?
How many miles will Lanna run by day 10?

where the graph

Step-by-step explanation:

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
