Write an equation in slope for a line that passes through (3,4) (and has a y intercept of -8)
Vlad [161]

Answer:

Part 1) The equation in slope intercept form is y=4x-8

Step-by-step explanation:

Part 1) Write an equation in slope-intercept form for a line that passes through (3,4) (and has a y intercept of -8)

we know that

The equation of a line in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

we have

b=-8

point\ (3,4)

substitute

4=m(3)-8

solve for m

4+8=3m

3m=12

m=4

therefore

y=4x-8

F(x)=-3x • G(x) = x +7
kirill [66]

Answer:

-3x^2 - 21x

Step-by-step explanation:

This question is representing multiplying two functions :

We are finding f(x) * g(x)

We know that f(x) is -3x and g(x) is x + 7, therefore :

(-3x)(x + 7)

Follow FOIL :

First :

(-3x)(x)

-3x^2

Outer :

(-3x)(7)

-21x

Therefore the answer is :

-3x^2 - 21x
