0= 2x +2

-2x = 2

x= -1

Find the equation of the linear function represented by the table below in slope-intercept form.
Vitek1552 [10]

Answer:

y = 10x - 8

Step-by-step explanation:

The slope is "m", or how much the y-value changes on a line when the x-value changes by one.

The y-intercept is the y value of the line when it is intersecting the y-axis, or when the x-value is 0.

To find the slope, take 2 points from the graph and plug into the slope formula:

\frac{y_2-y_1}{x_2-x\\_1}

I'll use (0, -8) and (1,2).

Plug into the formula.

\frac{2--8}{1-0}

\frac{10}{1}

10

Slope = 10

To find the y-intercept, look at the table. What is the y-value when the x-value is equal to 0?

-8

y-intercept: -8

Slope-Intercept form:

y = mx + b

m: slope

b: y-intercept

y, x: leave as variables

y = 10x - 8

6(5+3) ÷ 2 in this equation how do I handle the 6? send help
Leya [2.2K]
First you have to solve the equation inside the parentheses. (5 + 3) = 8. Then you multiply,
6 • 8 = 48. After that just divide 48 by 2 and the answer is 24. Hope this helped.
