The slope equals zero and it passes through the point xy 19 x y 1 9. If b 0 the equation is a linear equation in the single variable y for every value of xIt has therefore a unique solution for y which is given by. Subtract from both sides of.
Write the equation in slope intercept form.
Subtract from both sides of. The slope-intercept form is where is the slope and is. Now to form a line once the y-intercept is plotted on the graph you can. The slope-intercept form is where is the slope and is the y-intercept.
