Aline has a slope of -1/2 and a y-intercept of –2. what is the x-intercept of the line?

x = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - and c = - 2, thus

y = - x - 2 ← equation of line

The x- intercept has a y- coordinate of zero.

Substitute y = 0 into the equation and solve for x

- x - 2 = 0

Multiply through by 2 to clear the fraction

- x - 4 = 0 ( add 4 to both sides )

- x = 4 ( multiply both sides by - 1 )

x = - 4

Thus the x- intercept is - 4

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
