Use the following graph to answer questions 1-3.1. what is the slope of the line? 2. what is the y intercept of the line? 3. write an equation for the line in slope-intercept form (y=mx + b)30 points will mark brainliest 30 points

m = 7/5

b = 7

y = 7/5x + 7

Step-by-step explanation:

points (-5,0)  (0,7)

slope  = (y2-y1)/ (x2-x1)

        = (7-0)/(0--5)

        = (7-0)/(0+5)

       = 7/5

y intercept = point where it crosses the y axis   (0,7)

y = mx+b

m = 7/5

b = 7

y = 7/5x + 7

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
