How do I rewrite an equation in slope intercept form and graph the line?
Example they gave was 7x + 4y=12 to be written as y=mx+b
I dont understand how adding -7 to each side ended up being -7/4x
Thank you kindly for helping
The equation is 7x + 4y = 12.
“Slope-intercept form of an equation of a line:
An equation of a line with slope m and y-intercept b is .”
The slope m of the non-vertical line can be expressed as follows.
That is, the slope of the line represents the rate of change of y with respect to the changes in x.
The slope and the y-intercept is computed as follows.
Rewrite the given equation as
Since 3 is the y-intercept, one of the point on the line will be (0,3) .
