Question

Asked Apr 16, 2019

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

Step 1

a)

*Given:*

The equation is 7x + 4y = 12.

*Known fact:*

“*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*.

Step 2

*Calculation:*

The slope and the *y*-intercept is computed as follows.

Rewrite the given equation as

Step 3

Since 3 is the *y*-intercept, one of the point on the line will be (0,3) .
