Find an equation of the line passing through each of the following pairs of points.
julia-pushkina [17]

For this graph the equation is x= -3

Because in the coordinates you gave, all the x values are -3 telling me that the line is a straight vertical line passing through the -3 x-axis and has no y-intercept as it's a vertical line, not diagonal, so it's not passing through the y-axis. Plus because of this too this line has no gradient.

Simplify 10 - [14 = (3 + 4) · 2]+3
lora16 [44]

Answer:

There is a typo near the equal sign.

There can be two different answers if we think that = sign as + or -.

First way: Making = as +

=> 10 - [14 + (3+4) x 2] +3

=> 10 - [14 + 7 x 2] + 3

=> 10 - [14 + 14] + 3

=> 10 - 28 + 3

=> 10 + 3 - 28

=> 13 - 28

=> -15

=> So, -15 is the answer if we consider "=" sign as "+" sign.

Second way: Making = as -

=> 10 - [14 - (3+4) x 2] + 3

=> 10 - [14 - 7 x 2] + 3

=> 10 - [14 - 14] + 3

=> 10 - 0 + 3

=> 10 + 3

=> 13

=> So, 13 is the answer if we consider "=" sign as "-" sign.
