Step-by-step explanation:

y=ax+b

if x = 0 then y = b=3

if x =1 then y= a+3=1 --> a=-2

so y = -2x + 3

Answer:

y = -2x + 3

Step-by-step explanation:

m = slope

b = y-intercept

y = mx + b

slope = change in y/change in x

slope = -2/1

y = -2x + 3

Troyanec [42]

IfIf it forms interior <6 measuring70. The measure of <4 is: B. 110°.

<h3>Measure of <4</h3>

Using this interior angle theorem

Measure of <4=180° - <6

Where:

<6 measure 70

Hence:

Measure of <4=180°-70°

Measure of <4=110°

Therefore the measure of <4 is: B. 110°.

May someone please help me on which to graph?
olga_2 [115]

Answer:

Option (4)

Step-by-step explanation:

Proportional relationship means,

y ∝ x

y = kx

k=\frac{y}{x}

Here, k = proportionality constant

Therefore, if the graph of a line passes through the origin (0, 0) table will represent the proportional relationship.

From table 1,

For a point (1, 2)

k=\frac{2}{1}=2

For another point (3, 2)

k=\frac{3}{2}=1.5

In both the cases 'k' is not same of constant.

Therefore, table (1) is not proportional.

For table (2),

Line passes through (2, 0).

That means there is a x-intercept → (2, 0)

Therefore, table doesn't represent a proportional relationship.

For table (3),

Line passes through a point (0, 1)

It means given line has a y-intercept → y = 1

Therefore, table doesn't represent a proportional relationship.

For table (4),

Line of this table passes through two points (1, 3) and (2, 6)

k=\frac{3}{1}=3

k=\frac{6}{2}=3

Therefore, proportionality constant for the given table is 3.

Now we can graph table (4).
