Question

A student is attempting to find an equation for a line that passes through two points. Which statement best applies to the mathematical work shown below?

Given the points (1, –2) and (2, 3), to find the equation of the line that passes through the two points, I first find the slope. I find that 2003-10-01-00-00_files/i0250000.jpg. I then find the y-intercept by 2003-10-01-00-00_files/i0250001.jpg, which implies b = 1. Therefore, y = x + 1.

Answer 1

yes ;) i can't see the pics but if you have done these steps,you're correct ;)

Answer 2

but the slope is 5! you've made a mistake.

Answer 3

y2 - y1 / x2 - x1 is slope.

Answer 4

did i used the right formula to find the slope?

Answer 5

which formula you used?

Answer 6

Given the points (1, –2) and (2, 3), to find the equation of the line that passes through the two points, I first find the slope. I find that 2003-10-01-00-00_files/i0250000.jpg. I then find the y-intercept by 2003-10-01-00-00_files/i0250001.jpg, which implies b = 1. Therefore, y = x + 1.

Answer 7

i can't see the pics.attach them again!
