Choose the equation that satisfies the data in the table.<br> HELP!!!!
harina [27]

The equation of the line represented by the table in slope intercept form is; y = ²/₁₅x + 2

<h3>How to solve equation in slope intercept form?</h3>

The formula for equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

The y-intercept will occur when x = 0. Thus, from the table, it is clear hat the y-intercept will be c = 2.

Let us find the slope using the first two points;

m = (2 - 0)/(0 - (-15))

m = 2/15

Thus, the equation is;

y = ²/₁₅x + 2

4. CHF= 110

Step-by-step explanation:

3. AGH corresponds to CHF, so they equal the same. AGH = 150

4. BGE is vertical to AGH, so they equal the same AGH = 110. AGH corresponds to CHF, so they equal the same. CHF=110.
