Answer:

Step-by-step explanation:
Slope-intercept form means

where m is given its the slope which is
and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,




now we know the value of slope which is given
and we found the value of which is 1 so we put these values into our original slope-intercept form equation
