Complete the equation of the graphed linear function. Write the slope in decimal form.
erma4kov [3.2K]

Every straight line graph has an equation in the same form:

             y  =  (slope of the line) x  +  (y-intercept) .


-- The slope of the line is

     (how far it goes UP, going left to right between any 2 points)
divided by
     (how far it goes left to right between the same 2 points) .

The line on this graph has a slope of  + 1/2 .


-- The y-intercept is the point where the line crosses the y-axis.
The line on this graph crosses the y-axis at  -1 .

                       y  =  (slope of the line) x  +  (y-intercept) .                     

                       y  =      ( 0.5 ) x                            ( - 1 ) .
