Start with the simplest equation of a straight line: y = mx + b.
Subst. 1 for m, 2 for x and 4 for y. Then, 4 = 1(2) + b, or b = 2.
In slope-intercept form, the equation of this line is y = x + 2.
Answer:
To find the Hypotenuse the Pythagoras theorem is used
h² = a² + b²
h = hypotenuse
a = 15cm
b = 8cm
h = ?
h² = 15² + 8²
h = √225 + 64
h = √289
h = 17cm
The Hypotenuse is 17cm
Hope this helps.
Hello :
2x²+3x+1=0
a=2 b=3 c=1
b²-4ac = (3)²-4(2)(1) = 1
