Question

function a
function b
$y = 5x - 5$
which statement is true?
the y-intercept of function a is greater than the y-intercept of function b.
the y-intercept of function a is less than the y-intercept of function b.

Explanation:

Step1: Find y-intercept of Function A

The y-intercept is where the line crosses the y-axis (x=0). From the graph, this is at (0, 4), so y-intercept = 4.

Step2: Find y-intercept of Function B

Function B is in slope-intercept form $y=mx+b$, where $b$ is the y-intercept. For $y=5x-5$, $b=-5$, so y-intercept = -5.

Step3: Compare the two intercepts

Compare 4 and -5: $4 > -5$.

Answer:

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