Question

Please help me its linear equations.

Answer 1

• A: -5
• B: -6
• greater

Explanation:

You want the y-intercepts of the relation y -5 = -5/2(x +4) and the one shown in the graph.

Y-intercept

The y-intercept of a function is its value when x=0. It is the y-value where the graph crosses the y-axis.

A

Setting x=0, we can solve for y:

y -5 = -5/2(0 +4) = -10

y = -5 . . . . . . . . add 5; this is the y-intercept

The y-intercept of Line A is -5.

B

The graph crosses the y-axis at y = -6.

The y-intercept of Line B is -6.

The y-intercept of Line A is greater than the y-intercept of Line B.
