HELP ITS ABOUT POINTS AND EQUATIONS AND WHAT THE PERSON FAILED IN DOING EXPLANATION NEEDED PLEASE

Answer:
see below
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation
Answer:
y = 0.5x - 6
Step-by-step explanation:
(-3. -7.5) ; (2 , -5)
![Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-5-[-7.5]}{2-[-3]}\\\\=\frac{-5+7.5}{2+3}\\\\=\frac{2.5}{5}\\\\=0.5](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-5-%5B-7.5%5D%7D%7B2-%5B-3%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-5%2B7.5%7D%7B2%2B3%7D%5C%5C%5C%5C%3D%5Cfrac%7B2.5%7D%7B5%7D%5C%5C%5C%5C%3D0.5)
m = 0.5 ; (2, -5)
equation of line : y-y1 = m(x-x1}
y -[-5]=0.5(x - 2)
y + 5 = 0.5x - 0.5*2
y + 5 = 0.5x - 1
y = 0.5x - 1 -5
y = 0.5x - 6
