Answer:
b
Step-by-step explanation:
The greatest common factor is the largest value two numbers share in common which multiplies to each of the numbers.
7ab has factors 7, a, b
has factors 2, 4, 8, b, b, b
These share in common b.
Correct answer: y = x + 2
To find out the slope, you would need to remember this slope formula: . We can use the two points provided on the graph to figure out the slope. We can label (3, 3) as
and
, and (0, 2) as
and
. Now we can plug these numbers into the slope formula to find out the slope:
m = →
→
→
To find out the y-intercept, just substitute (3, 3) into the slope-intercept<em> </em>formula ( <em>y = mx + b</em> ) with the slope that is substituted for '<em>m</em>' that we already solved earlier.
y = mx + b
(3) = (3) + b
3 = 1 + b
2 = b
You can also prove this true by looking at the graph provided. The line intersects at the y-axis at 2.
Now we know that m = and b = 2, we can substitute it into the slope-intercept formula. Thus, the answer is y =
x + 2.
