Participant A runs at a slower rate than Participant B. Both participants run at a constant rate. This table represents Participant A.

Time (min) 5 8 12 15
Number of laps run 2.75 4.4 6.6 8.25
Which equation could represent Participant B?

Time in minutes is represented by x and number of laps run is represented by y.

Select each correct answer.

y = 0.3x

y = 0.7x

y = 0.5x

y = 0.9x

my answer was 0.7x and 0.9x
please check my answer

nope.   happens to me as well.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

you first to choose the points and then move from then as the slope you have
