The line's y-intercept is -3 as per the information given in the table.
<h3>What is meant by slope?</h3>
The slope or gradient of a line is a numerical representation of a line's steepness and direction in mathematics. The reason for this usage is unknown, but it first appears in English in O'Brien (1844), who wrote the equation for a straight line as y = mx + b, and in Todhunter (1888), who wrote it as y = mx + c. In this case, m stands for the line's slope.
Slope is the result of calculating the ratio of vertical change to horizontal change between (any) two distinct points on a line.
We know that,
y=m x +c
From the table the points are,
A(-2,5)
B(-1,1)
C(0,-3)
D(1,-7)
Substituting the C point in the above equation we get,
-3=m(0)+c
c=-3
Consequently, the line's y-intercept is -3.

Answer:
first number= 19/5
second number= 2/5
Step-by-step explanation:
first number= a
second number= b
a+3b=5 equation 1
b+2a=8 equation 2
using equation 2 we have
b=8-2a
using equation 1 we have
a+3(8-2a)=5
a+24-6a=5
24-5=6a-a
19=5a
a=19/5 = first number
so using b=8-2a
we have
b=8-2(19/5)
b=8-(38/5)
b=2/5 = second number
Answer:
3
Step-by-step explanation:
Any number and variable combined is a term.
So 8 (#1 - Constant), + 19y (#2 -Coefficient + Variable), - 4z (#3 -Coefficient + Variable)
3 terms - B
I think it is (10,-7) but lmk otherwise
