Question

Write the equation in standard form of the line that passes through the points (7,-3) and (-3,1).​

Answer 1

Standard Form: 4/10x + y = -0.2

Explanation:

(7,-3) and (-3,1)

m = y2 - y1/x2 - x1

m = 1 - (-3)/-3 - 7

m = 1 + 3/-10

m = -4/10

y - y1 = m(x - x1)

y - 1 = -4/10(x + 3)

y - 1 = -4/10x - 1.2

y = -4/10x - 1.2 + 1

y = -4/10x - 0.2

Standard form: Ax + By = C

y = -4/10x - 0.2

4/10x + y = -0.2

Answer 2

y-intercept form of that equation:

y=-2/5x+b

1=-2/5(-3)+b

1=6/5+b

b=-1/5

y=-2/5x-1/5

standard form:

2/5x+y=-1/5

srry im too busy rn so i couldnt explain very well :/
