–8x + y = 9
y = [ ]x + [ ]
y = 8x + 9
To find the slope-intercept form of the given equation, we can rearrange the equation to solve for y in terms of x.
Given:
-8x + y = 9
To isolate y, we can add 8x to both sides of the equation:
-8x + 8x + y = 9 + 8x
Simplifying the equation:
y = 8x + 9
So, the slope-intercept form of the equation is y = 8x + 9. The coefficient of x (8) represents the slope, and the constant term (9) represents the y-intercept.
To write the equation y = mx + b in slope-intercept form, we need to find the values of m and b.
Given the equation -8x + y = 9, we can rearrange it to solve for y:
y = 8x + 9
So, the value of m is 8 and the value of b is 9. Therefore, the equation y = 8x + 9 is in slope-intercept form.
