Write an equation of the line that passes through the given point and has the given slope -1,4, slope -2

y = -2x + 2

Step-by-step explanation:

You need to use the Slope intercept formula- y = mx + b

You coordinate is (-1,4) X = -1 and Y = 4

All you need to do is substitute the points into the formula and solve

M in the formula is the slope: which is -2

1. y = mx + b

2. (4) = -2(-1) + b (multiple -2 and -1) (negative and a negative make a positive)

3. 4 = 2 + b (Subtract 2 from both sides)

4. 2 = b (this is your final answer)

5. Just put everything together with the answers in the equation :

y = -2x + 2

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
