Write an equation for the line in slope-intercept form.
STatiana [176]

Answer:

y=2x+2

Step-by-step explanation:

the equation for slope intercept form is y=mx+b where b is the y intercept and m is the slope. From the graph we can see that where x is 0 y is 2 which makes 2 be the y intercept, and when x is 1 y is 4 which then you replace y for 4 and x for 1 which would be 4=m(1)+2,now u subtract 2 from both sides which leaves you with 2=m(1) and m times 1 is m so now your left with 2=m which means the slop is 2

41 + 86 + 133 + x equals
Virty [35]
We would first just add up the numbers without the x in our way.

\sf41 + 86 + 133= 260

And then afterward, we wouldn't be able to add x based on the fact that it would then be viewed as multiplication, therefore your answer would then be below.

 Your correct answer would then be \sf260+x
