Lets say the number we are solving for is a

\sf{ 7 \times a = 31}

Divide 7 on both sides

\sf{ \frac{7 \times a}{7} = \frac{31}{7}}

\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\huge{\sf{a =  \frac{31}{7}}}}}}}}}}}}}}}}}}}}}}}}}}}}}

7 (x) = 31

Divide both sides by 7.

7x/7 = 31/7

x = 31/7

Therefore, 7 * 31/7 = 31

Y-intercept = (0, 2)<br> slope = -3/7 what is the equation?
Marianna [84]

Answer:

y = -(3/7)x + 2

Step-by-step explanation:

(see attached)

recall that the slope-intercept form of a linear equation is

y = mx + b

where m = slope = given as -(3/7)

and b = y-intercept = 2

substituting these values into the eqation:

y = mx + b

y = -(3/7)x + 2

The equation of line GH is y = 4x − 3. Write an equation of a line perpendicular to line GH in slope-intercept form that contain
butalik [34]

Answer:

The equation of this line is y = -1/4x - 7/2

Step-by-step explanation:

To find this, we need to first look for the slope. Perpendicular slopes have opposite and reciprocal slopes. Since the original line has a slope of 4, this means the new one has a slope of -1/4.

Given that slope, we can find the equation by starting with the base form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the two coordinates in for (x1, y1).

y - 3 = -1/4(x - 2)

Now that we have this, solve for y for the slope-intercept form.

y - 3 = -1/4x + 1/2

y = -1/4x + 7/2
