Question

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

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) .
