Dropdown

What are the x and y intercepts for the following linear function

y ​ = 3x + 3  ?​ ​

Select answer

​ ​

Select answer

Multiple Choice

In an x intercept, which value is always 0?

• the x value

• the y value

• Standard form of a linear equation is Ax+By=C

• To put a line in standard form, we need our 'x' and 'y' terms on one side and our constant term on the other

​

Standard Form

Think of these as multi-step equations, where you must move both the x & y- values to the same side of the equation.

​

​Standard form is another way of converting Slope-Intercept form.

Multiple Choice

Which is correctly written in standard form of y=-6/7x+12

• 6x + 7y = 84

• 6/7x - y = 12

• y - 6/7x = 12
