y = 4x - 2

When y = 26, x = 7.

Step-by-step explanation:

Use the two points on the line to calculate the slope of the line, then use this slope and the y-intercept to write an equation for the line.

Slope formula:

(y2 - y1)/(x2 - x1)

We have these two points on the graph: (1, 2), (-1, -6).

Substitute these points into the slope formula and find the slope of the line.

(-6-2)/(-1-1)(-8)/(-2)4

The slope of the line is 4. Now, use the point-slope formula to write an equation for the line.

Point-slope formula:

y - y1 = m(x - x1)y - 2 = 4(x - 1)y -2 = 4x - 4 y = 4x - 2

To find the value of x when y = 26, substitute y = 26 into the equation and solve for x.

26 = 4x - 2 28 = 4x x = 7

Answer from: Carri425

First find slope
(y2-y1)/(x2-x2)
Use points (1,2) and (-1,-6)
(-6-2)/(-1-1) = -8/-2 = 4
Slope int equation: y = mx + b
m = slope, b = y intercept
Plug in what we know (use any point)
2 = 4(1) + b
2 = 4 + b, b = -2
Equation: y = 4x - 2
Plug in y = 26
26 = 4x - 2
28 = 4x, x = 7
Solution: x = 7

Answer from: Quest

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
