Take 2 points

(0,-3)
(1,1)

Slope:-

$\\ \sf\longmapsto m=\dfrac{1+3}{1}=4$

Equation of line in point slope form

$\\ \sf\longmapsto y-y_1=m(x-x_1)$

$\\ \sf\longmapsto y+3=4x$

$\\ \sf\longmapsto y=4x-3$

Answer:

C. y = 4x - 3

Step-by-step explanation:

The line has a positive slope and negative y-intercept.

m = 4, b = - 3

This is only matched by a choice C

-2 4/5 + 1/4 equals what ?

vlada-n [284]

Hey there! :)

Since 2 4/5 is greater than 1/4, the answer is negative.

You can just subtract 2 4/5 and 1/4 and add the (-) sign

2 4/5 - 1/4

Change the fractions so they can have a common denominator: 20

2 4/5 = 2 16/20

1/4 = 5/20

2 16/20 - 5/20 = 2 11/20

Add the (-) sign → -2 11/20

Answer ⇒ -2 11/20
