PLEASE HELP!! Will give brainliest if you give explanation!
MArishka [77]
The equation in slope-intercept is   y=0.625x+7.    


y = mx + b

where: 
m is the slope of the line 
b is the y-intercept of the line

The slope m of the line through any two points (x1, y1) and (x2, y2) is given by:

The y-intercept b of the line is the value of y at the point where the line crosses the y axis. Since for point (x1, y1) we have y1 = mx1 + b, the y-intercept b can be calculated by:

b = y1 - mx<span>1.    hope that helped</span>
