A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.
It looks like you have to do distance formula. It's basically this:
D =
(ignore the A, i dont know how to get rid of it sorry)
I would then plug in the points of A(1,7) and B(10,3).
D = 
Then I would get the square root of 4^2 + 9^2
= square root of 16 + 81
= square root of 97
So the length of AB would be the square root of 97
You should probably post the equation if you need help
Answer:
Slope: -10
Y-intercept: 50
X-intercept: 5
Step-by-step explanation:
y-mx+b
y=-10x+50
- m is slope so, slope is -10
- plug in 0 for x and solve to get y-intercept y=-10(0)+50 , y intercept is 50
- plug in 0 for y and solve to get x-intercept 0=-10x+50, x-intercept is 5
