y = -4x +1

Step-by-step explanation:

The slope-intercept form of a straight line is

y = mx +b

The formula for the slope (m) is

m = (y₂ - y₁)/(x₂ - x₁)

The two points on the line are

(-1, 5) and (1, -3)

m = (-3 – 5)/[1 – (-1)]      Substitute the values

m = -8/(1+1)

m = -8/2

m = -4

Substitute the value of m into the general formula.

y = -4x  + b

At (-1, 5)

5 = -4(-1) + b     Remove parentheses

5 = 4 + b          Subtract 4 from each side

b = 1

The equation of the straight line is y = -4x +1.

a² + b²= c²

24² + 7² = c²

c= 25
