Write the Equation of the line in fully simplified slope- intercept form

y=(-13/9)x-2

Step-by-step explanation:

Slope = m = (y₂-y1)/(x₂-x1) = (-8-5)/(4-(-5)) = -13/9

Y-intercept = b = (0,-2)

Final equation: y=-13/9x-2

y=1.1x-2

Step-by-step explanation:

y=mx+b

Its sloping downwards, so a negative slope.

two points: (-5,4) and (5,-8)

so first find the slope.

y2-y1 / x2-x1  <= formula

so: -8-(4) / 5-(-5)

which becomes => -11 / 10

which is -1.1 the slope is -1.1

plug this into y=mx+b, where m is the slope

so: y=1.1x+b

obviously b is the y intercept, where the line meets y

the y intercept is -2

s final answer is

y=1.1x+(-2)

becomes y=1.1x-2

f(x) = y

f(-3) = -5
