To get the determinant of a 2*2 matrix, you subtract the product of the leading diagonal from the secondary diagonal.

In the matrix above, the product of the secondary diagonal is (4×5) = 20.
The product of the leading diagonal is (-2×3) = -6.

∴ determinant(Δ) = (-6) - 20 = -26

What is the y-intercept of the line given by the equation below Y=4x-6

Irina18 [472]

Answer:

the y-intecept of the line is (0, -6)

Step-by-step explanation:

Given the linear equation in slope-intercept form: y = mx + b

where:

m = slope = 4

b = y-intercept = -6

The y-intercept is the value of y when x = 0.

Plug x = 0 into the equation to solve for the y-intercept:

y = 4x - 6

y = 4(0) - 6

y = 0 - 6

y = -6

Therefore, the y-intecept of the line is (0, -6)
