Answer:

$\huge\boxed{y = -5x - 4}$

Write an equation in the format y = mx + b, or the slope-intercept formula, where:

m = slope

b = y-intercept

Plug in the values given:

y = (-5)x + (-4)

Simplify:

y = -5x - 4. This is the equation in slope-intercept form.

Answer: y=-5x-4

Step-by-step explanation:

Slope intercept form is y=mx+b

Since m represents slope you will plug in -5 because that is your slope.

Since b represents the y-intercept, you will plug in -4 after y=-5x

so therefore your equation is y=-5x-4

What is the solution(s) to the system of equations y = x² +4 and y = 2x + 4

bija089 [108]

Answer:

$(x,y) = (0,4)~ \text{and}~ (x,y) = (2,8)$

Step by step explanation:

$y = x^2 +4~~~~~~~~~...(i)\\\\y = 2x +4~~~~~~~~~...(ii)\\\\\text{From (i) and (ii):}\\\\~~~~~~x^2 +4 = 2x+4\\\\\implies x^2 = 2x\\\\\implies x^2 -2x = 0\\\\\implies x(x-2) = 0\\\\\implies x =0,~ x = 2$

$\text{Substitute x = 0 in eq (i):}\\\\y = 0^2 +4 = 4\\\\\text{Substitute x = 2 in eq (i):}\\\\y=2^2+4 = 4+4 = 8\\\\\text{Hence,}~ (x,y)= \{(2,8), (0,4)\}$
