Answer:
D. y = 1/2x + 3/2
Explanation:
You probably already know the point slope equation:
y = m(x - x₀) + y₀
All you need is the slope and the (x₀, y₀).
The (x₀, y₀) could be solved by plugging in the given x=-1 value into the function.
m, the slope, is the same as a derivative; ie. a derivative is a slope.
So solve for the derivative and find the slope at x=-1.
Plug into point slope equation and simplify.
Answer:
At a point X = 1.5 and Y = 4, the two lines will intersect
Explanation:
Given,
Two lines will intersect at the point with co-ordinates (X, Y) that will satisfy both the equations.
Hence,
y = 4x - 2 - Eq 1
y = 7 - 2x - Eq 2
Solving Eq 1 & 2, we get -
Eq 1 -Eq 2 will give
0 = 6X -9
6X = 9
X = 1.5
Y = 7 - 2*1.5 = 7-3 = 4
At a point X = 1.5 and Y = 4, the two lines will intersect
This is called a direct current > ———
