How do you graph y=-x+8

Use the slope-intercept form to find the slope and y - intercept. The slope-intercept form is y=mx + b y = m ⁢ x + b, where m m is the slope and b b is the y - intercept. Find the values of m m and b b using the form y=mx + b y = m ⁢ x + b. The slope of the line is the value of m m, and the y - intercept is the value of b b.
