How can you determine the best method of solving a system of equations?

Elimination is best used when both equations are in standard form (Ax + By = C).

Elimination is also the best method to use if all of the variables have a coefficient other than 1.

Hope this helps

a line with a slope of 1 passes through the point (5,10). what is the equation in this slope-intercept form?

patriot [66]

Answer:

y=x+5

Step-by-step explanation:

So first you need to plug everything into the point-slope formula which is

y-y1=m(x-x1)

m being the slope and y1 and x1 being the point (5,10)

So once you plug it in it should look like this: y-10=1(x-5)

Now you solve it

First you need to distribute 1 in 1(x-5) which is (x-5)

Now you have y-10=x-5

Then you add 10 to both sides which is y=x+5

Your answer is y=x+5
