how to solve this
m=-2 and (2,4)


Sagot :

[tex]m=-2 \ and \ (2,4) \\ \\To \ find \ our \ equation \ we \ will \ use \ the \ formula: \\ \\ y - y _{1} = m(x - x _{1}) \\ \\ y-4=-2(x-2)\\\\y-4=-2x+4 \\ \\y=-2x+4+4\\ \\y=-2x+8[/tex]
m=-2 and (2,4)
we need this formula:
y=mx+b
how to get the formula, finding the slope:
b=y-mx
solution;
b=y-mx substitute:
b=4-(-2)(2)
b=8
