The given triangle is a right triangle.
It was given that,
and
Using the Pythagoras Theorem, we can determine the value of c.
The ratio is the adjacent over the hypotenuse.
We rationalize to get:
Answer:
y = 2x + 2
Step-by-step explanation:
<em>(a) Slope </em>
The point-slope formula for a straight line is
y₂ - y₁ = m(x₂ - x₁)
The line goes through the points (-1, 0) and (0, 2).
2 – 0 = m[0 – (-1)]
2 = m
(b) y-intercept
y = mx + b
Use the point (0, 2)
2 = 2× 0+ b
2 = 0 + b
b = 2
∴ y = 2x + 2
