A line passes through (-2, 3) and has a slope of 0.2. Write an equation of the line.
mars1129 [50]

Answer:

y = 0.2x + 3.4

Step-by-step explanation:

Slope intercept form of line is

y = mx + c

where

m = slope

c is y intercept

given that slope is 0.2 thus, m = 0.2

now equation of line

y = 0.2x + c

now we substitute value of x and y ( (-2, 3) in this equation as given that the given point passes through the line

3 = 0.2*-2 + c

3 = -0.4 + c

c = 3+0.4 = 3.4

put c = 3.4 in equation

y = 0.2x + c

y = 0.2x + 3.4

Thus,

third option , y = 0.2x + 3.4 is the correct answer

How do you solve 4-2 times -2 times -5+5×3
ddd [48]

Answer: -12

Step-by-step explanation:

4-2 equals 2. Multiply 2 by -2 (negative 2) and you'll get -4.

Then leave the -4 alone and move on to the other part of the question.

-5 plus 5 equals gives you 0. So drop the zero and you'll have only -4 and 3. Multiply those and you'll get -12.
