Aline passes through the point (2, 7) and has a slope of 4. What is the equation of the line?

solve for slope intercept form

y = mx + b

m represents the slope, which is 4

and b represents your y intercept

y = 4x + b

          you have a table of values  where the x & y represent in the equation all of the different x & y coordinates that make up the line.

we have an x & a y coordinate (2, 7)

since we already know what the slope is and I need to solve for b you can now plug in the x point.

y = 4(2) + b

7 = 8 + b

we need to get b on one side so we subtract 8 from both sides

7 - 8 = 8 + b - 8

-1 = b

So the equation of the line is

y = 4x - 1

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
