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
Answer:
(-9, 10)
Step-by-step explanation:
The location of the midpoint of a line with endpoint at () and (
) is given as (x, y). The location of x and y are:
Given the endpoint (9,8) and Midpoint (0,9), the location of the other endpoint can be gotten from:
Hence the endpoint is at (x2, y2) which is at (-9, 10)
