Answer:

Multiply 1st equation by 3

Step-by-step explanation:

To eliminate -3y, we must multiply the 1st equation by such a number that the -y becomes -3y. This can be done by multiplying the 1st equation by 3.

Find the equation of the linear function represented by the table below in slope-intercept form.
Ilya [14]

Answer:

the desired equation is y = x + 4.

Step-by-step explanation:

Slope is defined as m = rise over run.  Run is the change (usually an increase) in x, and rise an increase or decrease in y.

We see, in the table, that if x increases from 1 to 6 (a 'run' of 5), y increases from 5 to 10 (a 'rise' of 5).  Thus, it's immediately apparent that the slope is m = rise / run = 5 / 5, or just 1.

Using the slope-intercept form of the equation of a straight line, y = mx + b, and the point (1, 5), we calculate b:

5 = 1(1) + b, or b = 4.

Therefore the desired equation is y = x + 4.

How would the graph change if the b value in the equation is decreased but remains greater than 1? Check all that apply.
Harrizon [31]

Answer:

The graph will begin on a lower point on the y-axis.

The y-values will continue to increase as x increases.
