Write the point-slope equation of the line that goes through (1, 4) with a slope of -10

sammy [17]

Answer:

y-4=-10(x-1)

Step-by-step explanation:

Point-slope form is:

$y-y_1=m(x-x_1)\\m-slope\\(x_1,y_1)-point$

We are given the slope of -10 and the point (1,4). So:

m = -10

x1 = 1

y1= 4

Replace the appropriate values:

$y-4=-10(x-1)$

So, y-4=-10(x-1) should be the point-slope equation.

Can someone help me on this math problem ?

faltersainse [42]

Answer:

4/3

Step-by-step explanation:

Given two points, we can find the slope by using

m = (y2-y1)/(x2-x1)

= (20 - -16)/(7 - -20)

= (20+16)/(7+20)

= 36/27

=4/3

What is the number whose 4/5 is 144?

anyanavicka [17]

Answer:

180

Step-by-step explanation:

Multiply 144 by the reciprocal of $\frac{4}{5}$ , that is

The reciprocal of $\frac{4}{5}$ is $\frac{1}{\frac{4}{5} }$ = $\frac{5}{4}$ , then

$\frac{5}{4}$ × 144 = $\frac{5(144)}{4}$ = 180
