Answer:
Step-by-step explanation:
Slope-intercept form is where m is the slope
A. The slope is 8/5, and the -1/2 means that the point (0, -1/2) falls on the line, therefore the slope-intercept form is y+1/2=8/5(x-0) or y+1/2=8/5x
B. The slope is -5/8, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=-5/8(x-0) or y+1/2=-5/8x
C. The slope is 5/8, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=5/8(x-0) or y-1/2=5/8x
D. The slope is 8/5, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=8/5(x-0) or y-1/2=8/5x
