Helena wrote the equation using point-slope form for the line that passes through the points (5, 1) and (3, 5). analyze the steps of her work using the point-slope form to write the equation. equation in which step did helena make an error? in step 1, she substituted the x values for y and the y values for x. in step 2, she didn’t use an x and y from the same coordinate pair. in step 3, she solved for the wrong variable. helena did not make an error.

In step 2, she didn’t use an x and y from the same coordinate pair

Step-by-step explanation:

see the attached figure to better understand the problem

we have the points (5, 1) and (3, 5)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

substitute

step 2

The equation of the line in point slope form is

take the point (3,5)

substitute

step 3

therefore

In step 2, she didn’t use an x and y from the same coordinate pair

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

so mark-up is 0.4 multiplied by 180 = 72
