How do I work out 5x+y=-10? I'm doing slope- intercept form at school and this is an example of one of them.
The slope-intercept form of the equation of a line is typically written as,
y = mx + b
where, m is the slope of the line and b is the y-intercept (value of y when x=0).
You can rearrange your equation to this form.
For example, the given equation can be rewritten as:
5x + y = -10
or y = -5x-10
comparing this with the typical slope-intercept form of equation of line, we can see that
m = -5 and b = -10
So, by rearranging the given equation we can achieve the slope-intercept form and obtain the slope and intercept of the given line.
