Write the points (-3,5) and (1,1) in slope-intercept form

1 answer:

3 0

Y=mx+b
m=slope
b=yint

find slope
slope between (x1,y1) and (x2,y2) is (y1-y2)/(x1-x2)

given
(-3,5) and (1,1)
slope=(5-1)/(-3-1)=4/-4=-1

y=-1x+b
find b
when x=1, then y=1
1=-1(1)+b
1=-1+b
add 1
2=b

y=-x+2

1.What values could replace the "?" in these equations to make them true?

Inga [223]

Answer:

Remember that logarithms are inverse of exponentials. That means the result of the logarithm is equal to the exponent of a power with the same base.

$log_{10} (10)=1$

Notice that the result is one beacuse $10^{1}=10$

$log_{10}(10000)=4$

Because $10^{4}=10000$

$log_{10}(?) =7 \implies 10^{7} =10000000$

So, $log_{10}(10000000)=7$

I would say to thim that $x$ and $y$ are variables of the logarithm, which be solved by imagine the logarithm as an exponential like

$log_{10} (x)=y \implies 10^{y}=x$

In other words, the $y$ is the exponent and the $x$ is the result of the exponential.
