You'll need to create two equations and have a 'system of equations' then use direct substitution to turn the equation into one. Whichever equation is easiest to solve for x or y. Solve that one for x or y and plug the result in for the variable in the other equation. Then you will have an equation with only 1 unknown.

A line has a slope of 7 and passes through the point (-2,-1) What is its equation in point-slope form?

elena-s [515]

Answer:

y + 1 = 7(x + 2).

Step-by-step explanation:

Point slope form:

y - y1 =m(x - x1).

Here m = 7 and (x1, y1) = (-2, -1)

So the answer is;

y - (-1) = 7(x - (-2))

Find the slope of the line in simplest form.

N76 [4]

Answer:

$-\frac{3}{2}$

Step-by-step explanation:

To find the slope of the given line, slope is the rise divided by the run of a line.

Slope = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

Picking points (4, 18) and (8, 12)

Now;

x₁ = 4

y₁ = 18

x₂ = 8

y₂ = 12

Slope = $\frac{12 - 18}{8-4}$ = $-\frac{6}{4}$ = $-\frac{3}{2}$
