please check my answer
Which of the following is an equation of a line with a slope of 4 and a y-intercept of -1?
A y = 4x — 1
B y = 4x + 1***
C y = – 1x + 4
D y = – 1x — 4
close ... you got the slope right
so is it a
yup
To check whether your answer is correct, we need to use the equation of a line in slope-intercept form, which is given by:
y = mx + b
where:
- m is the slope of the line
- b is the y-intercept
From the given question, we are looking for a line with a slope of 4 and a y-intercept of -1. Let's check each option:
A) y = 4x - 1
The slope is correct, but the y-intercept is incorrect. So, this option is not correct.
B) y = 4x + 1
This option has both the correct slope and y-intercept. So, this could be the correct answer.
C) y = -1x + 4
The slope is incorrect, as it should be positive (+4). So, this option is not correct.
D) y = -1x - 4
Both the slope and y-intercept are incorrect. So, this option is not correct.
Based on the analysis, it appears that option B (y = 4x + 1) is the correct equation of a line with a slope of 4 and a y-intercept of -1.
