The equation of a horizontal line is y b where b is the y-intercept. You can use either 35 or 611. It was changed to y -1x 12 so it will look like y mx b slope intercept form.
Pick any of the two given points.
Substitute the known values into the slope formula and simplify if necessary. For the equation y mx b m is the slope of the line that is multiplied by x and b is the y-intercept or we can say the point where the line will cross the vertical y-axis. Substitute the slope m in the slope-intercept form of the equation. The following line passes through the point 5 comma 8 and the equation of the line is y is equal to 1713x plus b.
