I need help. What’s the equation

Mathematics

1 answer:

Mekhanik [1.2K]3 years ago

6 0

Answer:

Step-by-step explanation:

y = mx + b

m = slope

so far what we know is

y = 1/2x + b

to find b we’ll plug in the point (2, 6)

6 = 1/2(2) + b

6 = 1 + b

b = 5

so now we plug in b to the equation to get

y = 1/2x + 5

MissTica

Answer:

$3.98(estimated)

Step-by-step explanation:

3c (cake) + 2(2c - 11) (bread) = 5.87

3c + 4c - 22 = 5.87

7c - 22 = 5.87

7c = 5.87 + 22

7c = 27.87

c = 3.98

Consider the line through (-1, -4) and (1, 2). What is the slope (m) of the line?

zloy xaker [14]

Answer:

3

Explanation:

$\bold{\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(-1,\:-4\right),\:\left(x_2,\:y_2\right)=\left(1,\:2\right)}$

$\bold{m=\frac{2-\left(-4\right)}{1-\left(-1\right)}}$

Find the gradients of line a and b

34kurt

Answer:

3 and - 4

Step-by-step explanation:

Calculate the gradients using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

Line A

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 1) ← 2 points on the line

m = $\frac{1+2}{1-0}$ = 3

Line B

with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (0, 5) ← 2 points on the line

m = $\frac{5-1}{0-1}$ = $\frac{4}{-1}$ = - 4
