Find the y and the x intercepts of the graph of the equation of y=3x+1
BaLLatris [955]

Answer:

x-intercept ⇨ -1/3

y-intercept ⇨ 1

Step-by-step explanation:

⟺ Finding the x-intercept, substitute y = 0

y=3x+1\\0=3x+1\\3x+1=0\\

Move 1 to subtract the another side.

3x=-1

Then move 3 to divide -1, leaving only x as a subject since we want to find the x-intercept.

x=-\frac{1}{3} #

⟺ Finding the y-intercept, substitute x = 0

y=3x+1\\y=3(0)+1\\y=0+1

y=1 #

Tips:

Here's the tips about finding the intercepts of the graph.

⟺ For x-intercept, It's like solving an equation to find the x-term.

⟺ For y-intercept, It's like using the constant to answer.

As for y = mx+b where m = slope and b = y-intercept.

For a linear function, It's not necessary to substitute x = 0 just to find y-intercept as we can answer the constant as our y-intercept.

Identify the constant of proportionality for each direct variation below.
andriy [413]

Answer:

see explanation

Step-by-step explanation:

The equation of 2 quantities in direct proportion is

y = kx ← k is the constant of proportionality

1

y = - 4x ← in standard form

with k = - 4

2

\frac{y}{x} = 2 ( multiply both sides by x )

y = 2x ← in standard form

with k = 2

3

\frac{x}{y} = 3 ( multiply both sides by y )

x = 3y ( divide both sides by 3 )

\frac{1}{3} x = y ← in standard form

with k = \frac{1}{3}

A. When solving the system of linear equations 6x+y = 1 and 7x+2y = -3 with substitution, it is easiest to first solve the equat
nalin [4]

Answer:

6x + y = 1

y = 1 - 6x

7x + 2(1 - 6x) = -3 substitute 1 - 6x in for y

7x + 2 - 12x = -3 combine like terms

2 - 5x = -3 subtract 2 from both sides

-5x = -5 divide by -5

x = 1
