Answer:
62
Step-by-step explanation:
well, we start by expressing the number:
a b
we understand that using the above expression, the value of the number is 10a + b
using the information in the question,
a = 3b (1)
and,
11b + 11a = 88 (2) (derived using 10a + b form)
hence, when substituting (1) into (2):
11b + 33b = 88
44b = 88
b = 2 (3)
sub (3) into (1)
a = 6
hence, the number is 62
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of aline:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

From the graph we have the points:
(-2, -5)
y-intercept (0, 3) → <em>b = 3</em>
Calculate the slope:

Put the value of the slope and the y-intercept to the equation of a line:

The rise is 1 and the run is 7
