What is the equation of a line with slope 3 and y-intercept negative 2?
A
y = 3x + 2
B
y = -3x + 2
C
y = 3x - 2
D
y = -3x - 2
Correct Answer: Option C — y = 3x - 2
Explanation:
Slope-intercept form: y = mx + c where m = slope and c = y-intercept. With m=3 and c=-2 the equation is y = 3x - 2. Coordinate geometry incl...
Slope-intercept form: y = mx + c where m = slope and c = y-intercept. With m=3 and c=-2 the equation is y = 3x - 2. Coordinate geometry including line equations slopes intercepts distances and midpoints is consistently tested at all competitive exam levels from NTS to CSS.
