Question

The y-intercept and slope, respectively, of a straight line are given. Find the equation of the line.
-$6.4$ and $- 1$  
A)$y - 6.4 x = 1$
B) $y = 6.4 x - 1$
C) $y = 6.4 - x$
D) $y = 6.4 + x$

Quizplus · Accepted Answer

The equation of a line in slope-intercept form is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. Given a slope of $-1$ and a y-intercept of $6.4$, the equation becomes $y = -1x + 6.4$ or simplified to $y = 6.4 - x$.

The Y-Intercept and Slope, Respectively, of a Straight Line Are 6.46.46.4

The Y-Intercept and Slope, Respectively, of a Straight Line Are $6.4$
