Question

-2x + 8

what the
is this

Answer 1

This is an algebraic expression.

Explanation:

This is an algebraic expression. It represents a linear function in which the variable "x" is multiplied by -2 and then 8 is added to the result. In mathematical terms, it represents a straight line with a slope of -2 and a y-intercept of 8. If we were to plot this expression on a graph, the line would have a negative slope and would cross the y-axis at the point (0, 8). The expression can be used to model a relationship between two variables, such as the relationship between time and distance, or between temperature and pressure, for example.

Answer 2

Answer: linear function y=-2x+8, x-intercept at x=4, y-int at (0,8)

Explanation:

if it is set equal to y, it is a linear function y=-2x+8, and if set equal to zero, it is an x-intercept to be solved. If an x-intercept is x=4 as you get x by itself by moving the eight over by subtracting and then dividing by negative 2.

(hope it helps as I am not sure what you are asking)

it is -2 multiplied by a number of x, plus 8
